2005 Redundant Functions
Dec 4, 2007
Hi All,
I recently updated my Sql Server 2000 to 2005. I have around 150 stored procedures which are used to produce reporting.
They all worked perfect on 2000 and I was wondering if there were any redundant function or changes in syntax in the 2005 that i should look out for.
Can anyone assist?
Many thanks in advance,
Kurt

I was playing around with the new SQL 2005 CLR functionality andremembered this discussion that I had with Erland Sommarskog concerningperformance of scalar UDFs some time ago (See "Calling sp_oa* infunction" in this newsgroup). In that discussion, Erland made thefollowing comment about UDFs in SQL 2005:[color=blue][color=green]>>The good news is that in SQL 2005, Microsoft has addressed several of[/color][/color]these issues, and the cost of a UDF is not as severe there. In fact fora complex expression, a UDF in written a CLR language may be fasterthanthe corresponding expression using built-in T-SQL functions.<<I thought the I would put this to the test using some of the same SQLas before, but adding a simple scalar CLR UDF into the mix. The testinvolved querying a simple table with about 300,000 rows. Thescenarios are as follows:(A) Use a simple CASE function to calculate a column(B) Use a simple CASE function to calculate a column and as a criterionin the WHERE clause(C) Use a scalar UDF to calculate a column(D) Use a scalar UDF to calculate a column and as a criterion in theWHERE clause(E) Use a scalar CLR UDF to calculate a column(F) Use a scalar CLR UDF to calculate a column and as a criterion inthe WHERE clauseA sample of the results is as follows (time in milliseconds):(295310 row(s) affected)A: 1563(150003 row(s) affected)B: 906(295310 row(s) affected)C: 2703(150003 row(s) affected)D: 2533(295310 row(s) affected)E: 2060(150003 row(s) affected)F: 2190The scalar CLR UDF function was significantly faster than the classicscalar UDF, even for this very simple function. Perhaps a more complexfunction would have shown even a greater difference. Based on this, Imust conclude that Erland was right. Of course, it's still faster tostick with basic built-in functions like CASE.In another test, I decided to run some queries to compare built-inaggregates vs. a couple of simple CLR aggregates as follows:(G) Calculate averages by group using the built-in AVG aggregate(H) Calculate averages by group using a CLR aggregate that similatesthe built-in AVG aggregate(I) Calculate a "trimmed" average by group (average excluding highestand lowest values) using built-in aggregates(J) Calculate a "trimmed" average by group using a CLR aggregatespecially designed for this purposeA sample of the results is as follows (time in milliseconds):(59 row(s) affected)G: 313(59 row(s) affected)H: 890(59 row(s) affected)I: 216(59 row(s) affected)J: 846It seems that the CLR aggregates came with a significant performancepenalty over the built-in aggregates. Perhaps they would pay off if Iwere attempting a very complex type of aggregation. However, at thispoint I'm going to shy away from using these unless I can't find a wayto do the calculation with standard SQL.In a way, I'm happy that basic SQL still seems to be the fastest way toget things done. With the addition of the new CLR functionality, Isuspect that MS may be giving us developers enough rope to comfortablyhang ourselves if we're not careful.Bill E.Hollywood, FL------------------------------------------------------------------------- table TestAssignment, about 300,000 rowsCREATE TABLE [dbo].[TestAssignment]([TestAssignmentID] [int] NOT NULL,[ProductID] [int] NULL,[PercentPassed] [int] NULL,CONSTRAINT [PK_TestAssignment] PRIMARY KEY CLUSTERED([TestAssignmentID] ASC)--Scalar UDF in SQLCREATE FUNCTION [dbo].[fnIsEven](@intValue int)RETURNS bitASBEGINDeclare @bitReturnValue bitIf @intValue % 2 = 0Set @bitReturnValue=1ElseSet @bitReturnValue=0RETURN @bitReturnValueEND--Scalar CLR UDF/*using System;using System.Data;using System.Data.SqlClient;using System.Data.SqlTypes;using Microsoft.SqlServer.Server;public partial class UserDefinedFunctions{[Microsoft.SqlServer.Server.SqlFunction(IsDetermini stic=true,IsPrecise=true)]public static SqlBoolean IsEven(SqlInt32 value){if(value % 2 == 0){return true;}else{return false;}}};*/--Test #1--Scenario A - Query with calculated column--SELECT TestAssignmentID,CASE WHEN TestAssignmentID % 2=0 THEN 1 ELSE 0 END ASCalcColumnFROM TestAssignment--Scenario B - Query with calculated column as criterion--SELECT TestAssignmentID,CASE WHEN TestAssignmentID % 2=0 THEN 1 ELSE 0 END ASCalcColumnFROM TestAssignmentWHERE CASE WHEN TestAssignmentID % 2=0 THEN 1 ELSE 0 END=1--Scenario C - Query using scalar UDF--SELECT TestAssignmentID,dbo.fnIsEven(TestAssignmentID) AS CalcColumnFROM TestAssignment--Scenario D - Query using scalar UDF as crierion--SELECT TestAssignmentID,dbo.fnIsEven(TestAssignmentID) AS CalcColumnFROM TestAssignmentWHERE dbo.fnIsEven(TestAssignmentID)=1--Scenario E - Query using CLR scalar UDF--SELECT TestAssignmentID,dbo.fnIsEven_CLR(TestAssignmentID) AS CalcColumnFROM TestAssignment--Scenario F - Query using CLR scalar UDF as crierion--SELECT TestAssignmentID,dbo.fnIsEven_CLR(TestAssignmentID) AS CalcColumnFROM TestAssignmentWHERE dbo.fnIsEven(TestAssignmentID)=1--CLR Aggregate functions/*using System;using System.Data;using System.Data.SqlClient;using System.Data.SqlTypes;using Microsoft.SqlServer.Server;[Serializable][Microsoft.SqlServer.Server.SqlUserDefinedAggregate (Format.Native)]public struct Avg{public void Init(){this.numValues = 0;this.totalValue = 0;}public void Accumulate(SqlDouble Value){if (!Value.IsNull){this.numValues++;this.totalValue += Value;}}public void Merge(Avg Group){if (Group.numValues > 0){this.numValues += Group.numValues;this.totalValue += Group.totalValue;}}public SqlDouble Terminate(){if (numValues == 0){return SqlDouble.Null;}else{return (this.totalValue / this.numValues);}}// private accumulatorsprivate int numValues;private SqlDouble totalValue;}[Serializable][Microsoft.SqlServer.Server.SqlUserDefinedAggregate (Format.Native)]public struct TrimmedAvg{public void Init(){this.numValues = 0;this.totalValue = 0;this.minValue = SqlDouble.MaxValue;this.maxValue = SqlDouble.MinValue;}public void Accumulate(SqlDouble Value){if (!Value.IsNull){this.numValues++;this.totalValue += Value;if (Value < this.minValue)this.minValue = Value;if (Value > this.maxValue)this.maxValue = Value;}}public void Merge(TrimmedAvg Group){if (Group.numValues > 0){this.numValues += Group.numValues;this.totalValue += Group.totalValue;if (Group.minValue < this.minValue)this.minValue = Group.minValue;if (Group.maxValue > this.maxValue)this.maxValue = Group.maxValue;}}public SqlDouble Terminate(){if (this.numValues < 3)return SqlDouble.Null;else{this.numValues -= 2;this.totalValue -= this.minValue;this.totalValue -= this.maxValue;return (this.totalValue / this.numValues);}}// private accumulatorsprivate int numValues;private SqlDouble totalValue;private SqlDouble minValue;private SqlDouble maxValue;}*/--Test #2--Scenario G - Average Query using built-in aggregate--SELECT ProductID, Avg(Cast(PercentPassed AS float))FROM TestAssignmentGROUP BY ProductIDORDER BY ProductID--Scenario H - Average Query using CLR aggregate--SELECT ProductID, dbo.Avg_CLR(Cast(PercentPassed AS float)) AS AverageFROM TestAssignmentGROUP BY ProductIDORDER BY ProductID--Scenario I - Trimmed Average Query using built in aggregates/setoperations--SELECT A.ProductID,CaseWhen B.CountValues<3 Then NullElse Cast(A.Total-B.MaxValue-B.MinValue ASfloat)/Cast(B.CountValues-2 As float)End AS AverageFROM(SELECT ProductID, Sum(PercentPassed) AS TotalFROM TestAssignmentGROUP BY ProductID) ALEFT JOIN(SELECT ProductID,Max(PercentPassed) AS MaxValue,Min(PercentPassed) AS MinValue,Count(*) AS CountValuesFROM TestAssignmentWHERE PercentPassed Is Not NullGROUP BY ProductID) BON A.ProductID=B.ProductIDORDER BY A.ProductID--Scenario J - Trimmed Average Query using CLR aggregate--SELECT ProductID, dbo.TrimmedAvg_CLR(Cast(PercentPassed AS real)) ASAverageFROM TestAssignmentGROUP BY ProductIDORDER BY ProductID

Hi, good day everyone.
I would like to have a question here,
I want to configure a redundant SQL server. Let's said if server A is down, then server B can take over the workload of server A, and this is transparent to users which means they won't notify server A is down.
Besides the failover clustering method, is there any other solution?
My requirement is needed to run in Microsoft SQL 2000 standard edition and Microsoft Windows 2000 standard edition
Thanks,

The next script, gets redundant indexes, in a given database.
I run it in the query Analyzer, one statement at a time.
PLEASE: review the output, before drop any index.
USE ....
-- step 1
-- gets an tab,idx,col,order view
create view listaidxcols as
select SO.name as tabname,
SI.name as idxname,
IK.keyno as keyno,
SC.name as colname

syscolumns SC,
sysindexes SI,
sysobjects SO
where -- Link syscolumns
IK.id=SC.id
and IK.colid=SC.colid
-- Link sysindexes
and IK.id=SI.id
and IK.indid=SI.indid
-- Link sysObjects (tables)
and IK.id=SO.id
and SO.xtype='U'
-- no internal indexes
and SI.name not like '_WA_Sys_%'
and SI.name not like 'hind_%'
--step 2: view to get # of columns per index
create view cantcolsidx
as select tabname,

edit: this came out longer than I thought, any comments about anythinghere is greatly appreciated. thank you for readingMy system stores millions of records, each with fields like firstname,lastname, email address, city, state, zip, along with any number of userdefined fields. The application allows users to define message templateswith variables. They can then select a template, and for each variablein the template, type in a value or select a field.The system allows you to query for messages you've sent by specifyingcriteria for the variables (not the fields).This requirement has made it difficult to normalize my datamodel at allfor speed. What I have is this:[fieldindex]id int PKname nvarchartype datatype[recordindex]id int PK....[recordvalues]recordid int PKfieldid int PKvalue nvarcharwhenever messages are sent, I store which fields were mapped to whatvariables for that deployment. So the query with a variable criterialooks like this:select coalesce(vm.value, rv.value)from sentmessages sminner join variablemapping vm on vm.deploymentid=sm.deploymentidleft outer join recordvalues rv onrv.recordid=sm.recordid and rv.fieldid=vm.fieldidwhere coalesce(vm.value, rv.value) ....this model works pretty well for searching messages with variablecriteria and looking up variable values for a particular message. thebig problem I have is that the recordvalues table is HUGE, 1 millionrecords with 50 fields each = 50 million recordvalues rows. The value,two int columns plus the two indexes I have on the table make it into abeast. Importing data takes forever. Querying the records (with a fieldcriteria) also takes longer than it should.makes sense, the performance was largely IO bound.I decided to try and cut into that IO. looking at a recordvalues tablewith over 100 million rows in it, there were only about 3 million uniquevalues. so I split the recordvalues table into two tables:[recordvalues]recordid int PKfieldid int PKvalueid int[valueindex]id int PKvalue nvarchar (unique)now, valueindex holds 3 million unique values and recordvaluesreferences them by id. to my suprise this shaved only 500mb off a 4gbdatabase!importing didn't get any faster either, although it's no longer IO boundit appears the cpu as the new bottleneck outweighed the IO bottleneck.this is probably because I haven't optimized the queries for the newtables (was hoping it wouldn't be so hard w/o the IO problem).is there a better way to accomplish what I'm trying to do? (eliminatethe redundant data).. does SQL have built-in constructs to do stuff likethis? It seems like maybe I'm trying to duplicate functionality at ahigh level that may already exist at a lower level.IO is becoming a serious bottleneck.the million record 50 field csv file is only 500mb. I would've thoughtthat after eliminating all the redundant first name, city, last name,etc it would be less data and not 8x more!-GordonPosted Via Usenet.com Premium Usenet Newsgroup Services----------------------------------------------------------** SPEED ** RETENTION ** COMPLETION ** ANONYMITY **----------------------------------------------------------http://www.usenet.com

I'm looking for clarification around how SQL 2014 would get licensed if a server only has 1 of 2 CPU sockets in use (second socket being empty). I know the new license model is Core based, not Socket based. So does this mean that if I buy a "4 core pack" to cover my first CPU (quad core CPU), I am compliant with the license model? Or does Microsoft want me to license an empty socket with a Core Pack too? Its hard to find a rack mount server that only has 1 CPU socket. And the ones I do find don't have enough RAM slots or redundant power supplies.

All,
I have a situation where I need to identify redundant rows within a table. Here is the schema of the table:
create table Temp.Response (
TempKey int identity(1,1) not null primary key clustered,
ResponseId char(27) not null,
StudentUin char(9) not null,
TemplateId char(27) not null,
MidEndFlag char(3) not null
)
Here is a sample dataset that represents the production data:
TempKey | ResponseId | StudentUin | TemplateId | MidEndFlag

I need to identify the ResponseId values for rows that contain redundant StudentUin/TemplateId/MidEndFlag values, so that I can delete those rows. ResponseId, while not the primary key, is a unique value in this dataset. I thought I might use a cursor to parse this, but the real dataset is exceedingly large, and would like a set-based solution.
Best,
B.

Hello everybody,
have following problem:
I need info from 2 Tables. from the Table 2 I just need 1 column. When i ask for this column the output I get is data repeating themselve many times.
Distinct, should give me unique data, but is doesnt....
the code:
SELECT DISTINCT FSenddate, FSupplyIDName, FSupplyerNumber,FBillNo,FSourceBillNo,FItemName,FItemModel,
FAuxQty,FAuxTaxPrice,FHeadSelfP0237
FROM vwICBill_26
WHERE FSenddate BETWEEN DATEADD(dd,-14,GETDATE()) AND GETDATE()
This code just works in Table1 (vwICBill_26)
but with table 2 (vwICBill_1)
SELECT DISTINCT vwICBill_26.FSenddate,vwICBill_26.FSupplyIDName,
vwICBill_26.FSupplyerNumber,vwICBill_26.FBillNo,
vwICBill_26.FSourceBillNo,vwICBill_26.FItemName,
vwICBill_26.FItemModel,vwICBill_26.FAuxQty,
vwICBill_26.FAuxTaxPrice,vwICBill_26.FHeadSelfP0237,
vwICBill_1.FDate,vwICBill_1.FContractBillNo
FROM vwICBill_26,vwICBill_1
WHERE vwICBill_26.FSenddate BETWEEN DATEADD(dd,-14,GETDATE()) AND GETDATE()
AND vwICBill_1.FContractBillNo=vwICBill_26.FSourceBillNo
The last sentence is the problem
I want that it shows me the data that is not equal.
As soon as I implement the not equal it shows me the massive repeating data.
I mean even without the last sentence I get this data output.
All together, I want a clear database output without data repeating.
Any ideas how it may work without DISTINCT?
I think this problem is a typical amateure problem, but I would apreciate help!

Hi ,
I have a question about calling functions in SQl Server 2005.
Let's say that I have created as a dbo a function called Calculations.
If I want to call it from T-SQL I will write Select dbo.Calculations (arguments if any) etc.
My question is If I can skip the "dbo" part. Call the function without using the dbo .
Can I do that ?
Should I create the function as supervisor ? Does Sql Server has a property or something which will allow me to call the function without using the "dbo." ?
Thank you

User-Defined string Functions MS SQL Server 2005 Transact-SQL SQLCLR (VB. Net, C#.Net, C++. Net)
Ladies and Gentlemen,
I am pleased to offer, free of charge, the following string functions MS SQL Server 2005 Transact-SQL SQLCLR (VB. Net, C#.Net, C++. Net):
AT(): Returns the beginning numeric position of the nth occurrence of a character expression within another character expression, counting from the leftmost character.
RAT(): Returns the numeric position of the last (rightmost) occurrence of a character string within another character string.
OCCURS(): Returns the number of times a character expression occurs within another character expression (including overlaps).
OCCURS2(): Returns the number of times a character expression occurs within another character expression (excluding overlaps).
PADL(): Returns a string from an expression, padded with spaces or characters to a specified length on the left side.
PADR(): Returns a string from an expression, padded with spaces or characters to a specified length on the right side.
PADC(): Returns a string from an expression, padded with spaces or characters to a specified length on the both sides.
CHRTRAN(): Replaces each character in a character expression that matches a character in a second character expression with the corresponding character in a third character expression.
STRTRAN(): Searches a character expression for occurrences of a second character expression, and then replaces each occurrence with a third character expression. Unlike a built-in function Replace, STRTRAN has three additional parameters.
STRFILTER(): Removes all characters from a string except those specified.
GETWORDCOUNT(): Counts the words in a string.
GETWORDNUM(): Returns a specified word from a string.
GETALLWORDS(): Inserts the words from a string into the table.
PROPER(): Returns from a character expression a string capitalized as appropriate for proper names.
RCHARINDEX(): Similar to the Transact-SQL function Charindex, with a Right search.
ARABTOROMAN(): Returns the character Roman numeral equivalent of a specified numeric expression (from 1 to 3999).
ROMANTOARAB(): Returns the number equivalent of a specified character Roman numeral expression (from I to MMMCMXCIX).
AT, PADL, PADR, CHRTRAN, PROPER: Similar to the Oracle functions PL/SQL INSTR, LPAD, RPAD, TRANSLATE, INITCAP.
Plus, there are CHM files in English, French, Spanish, German and Russian.
Plus, there are versions for MS SQL SERVER, SYBASE ASA, DB2, Oracle.
More than 8000 people have already downloaded my functions. I hope you will find them useful as well.

WIthin SQL Server 2005, there are functions. This feature is new to me and I haven't found anyone that has written their own fucntions? I'm wondering if functions are written the same as stored procedures, and can a function be called from a stored procedure or even from within a query.

hello Im having a difficult time translating this query from Access to SQL because it uses the First/Last functions.
I have a 'Projects' Table and a 'Project_Comments' table, each has a 'Project_ID' field which links the 2 together. What I need to do is retrieve a Project List from the Projects Table and also the first Comment of each project based on the Commend_date field in the Project_Comments table. This is the MS ACCESS query:
SELECT Projects.Project_Number, Projects.Project_Name, First(Project Comments.Comment_Date), First(Project_Comments.Notes)
FROM Projects Left Join Projec_Comments ON
Projects.Project_Number = Project_Comments.Project_Number
GROUP BY Projects.Project_Number, Projects.Project_Name
Now I can use Min() for the Date instead of First, however I dont know what to do with the Notes field. Any help on how to get this over to sql would be greatly appreciated!

Hi,
I have created a function that returns a comma seperated list of product id's from a table. I need to call this function from a stored procedure to help filter my product results, something like the following:
SET @SQL = 'SELECT dbo.Products.ProductID FROM dbo.Products WHERE dbo.Products.ProductID IN (' + dbo.GetModels('dbo.Products.ProductID', '') + '))'
The problem I am having when executing the above is:
"Conversion failed when converting the varchar value 'dbo.Products.ProductID' to data type int."
Can anyone shed some light on how I can call the function, feeding through the product ID from the row of the select statement I am trying to execute (if this makes sense).
Any help would be great.

Hello,
I've created a function that performs modulo. I understand that SQL server 2000 / 2005 uses % for modulo, but we have an application that was written for Oracle. Oracle has a mod(dividend, divisor) function.
As to not rewite the queries, I would like to implement the function below:
the function executes properly but I must prefix it with the dbo schema.
Net: I can execute --- select dbo.mod(9,2) and it returns a 1 just like it should.
but I can not execute --- select mod(9,2) I receive the error "'mod' is not a recognized function name." on SQL 2000 and 2005.
If I can execute select mod(9,2) then I won't need to re-write any queries.
Also, on SQL 2005, I have tried to adjust the default shema, and the execute as clause, but neither helped my cause.
I'm going to try building the function in the CLR, but I think I will be faced with the same problem.
Can someone point me in the right direction?
Thanks
Tom
create function mod
(
@dividend int,
@divisor int
)
RETURNS int
as
begin
declare @mod int
select @mod = @dividend % @divisor
return @mod

Hi,
I have to calculate data in function with "EXEC". During runtime I get the Error:
"Only functions and extended stored procedures can be executed from within a function."
I would use a Stored Procedure, but the function is to be called from a view. I don't understand, why that should not be possible. Is there any way to shut that message down or to work around?
btw: Storing all the data in a table, would mean a lot of work, I rather not like to do. ;-)
Thx for any help

SELECT SUBSTRING(YEAR_MONTH, 1, 2) AS Expr1
FROM table1
I get a message which states that this command is not supported by the provider?
It works fine with other SQL tools like winsql?
thanks

Can someone explain what the different SQL CE DLL's functions are? I can issue a successful merge replication and these seem to be the DLL's loaded just after it completes.
RSSWM.exe base address: 2C000000
=========================
sqlceoledb30.dll 00CB0000 35000 A
sqlceca30.dll 00CF0000 75000 A
sqlceqp30.dll 00D70000 DD000 A
sqlcese30.dll 00E50000 6A000 A
sqlceer30en.dll 00EC0000 24000 A
itcnetreg.dll 00EF0000 15000 A
itcswinsock.dll 00F10000 D000 A
itc50.dll 00F30000 27000 A
sqlceme30.dll 00F70000 10000 A
rsshelper.dll 00F80000 6000 A
tcpconnectiona.dll 00F90000 10000 A
edbgtl.dll 00FA0000 14000 A
itceventlog.dll 01110000 B000 A
rsaenh.dll 01350000 2B000 RO, H, S, C, RAM from ROM
iq_lapi_c_wrapper.dll 01B80000 27000 RO, XIP
ssapi.dll 01BB0000 17000 RO, XIP
mscoree2_0.dll 01D90000 C3000 RO, H, S, XIP
After some application activity, I attempt a merge replication again and it fails with a "DLL could not be loaded" yadda, yadda message. These seem to be the loaded DLL's at this point.

I'm at a loss as to why SQL CE cannot load unless I am out of my 32MB of process space for some reason.
(App on an Intermec 751 with WM5 and 128MB RAM)
TIA for any help

I usually access stored procedures using SQL data source. But now I need a string returned from the database. If I write a function in SQL how do I access it from an aspx.vb file?

I hope this is a right form for ADO .net type of question.
My question is, can you call SQL function the way you call stored procedure from ADO .net. I coded it this way and does not seems to be getting result set back. The DataReader is seems to be coming back with nothing. Can someone post an example. I know you can write "SELECT udf_function()" but I really mean the way the stored procedure is called. Thanks.

20 // TODO: Add CLSReportManager.CLSGetSalesman implementation
21 BOSTx Tex = GetTx(CLSReportConstants.TrnMasterID.FQN2,"QueryRptSales");
22 try
23 {
24 string querySalesPerson = "SELECT dbo.BOS_GL_Workplace.WpszState, BOS_PI_Employee_1.szName, dbo.BOS_PI_Employee.szName AS Expr1, dbo.BOS_PI_Employee.szEmployeeId, "+

74
75 }
76 catch(Exception ex)
77 {
78 throw ex;
79 }
80
81 }
82 You see I want to make the query more dynamic. So instead of making the SQL parameter permanent I wanna make it dynamic, so the usercan choose whether they want to use the parameter or not. I already declare the parameter which is szSalesmanID. There's a function called AddQStrWhere which can make the query more dynamic. But the thing is when I wanna use the parameter it seems the code doesn't take it, it just use the regular query I dont know why.I already use the function but it just wont work, can you guys tell me what's wrong, Please I really do need some help from you guys, feelin; a lil' bit desperate in here.I appreciate any kinds of help, thanks. FYI: I use Visual Studio.NET 2003, SQL Server 2000.Best Regards.

I have a table that is used for employee evaluations. There are six questions that are scored either 1, 2, 3, 4, or 5. I want to tally the responses on a page, but I wonder if I can do it without 35 separate calls to the database (I also want to get the average response for each question). I know I can do "SELECT COUNT(intWorkQuality) AS Qual1 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '1' " and then "SELECT COUNT(intWorkQuality) AS Qual2 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '2' " and so on. But can I somehow do the aggregating at the page level, and just refer back to a datasource that uses a generic statement like "SELECT intWorkQuality, intDepend, intAnalyze, intWrite, intOral, intCompatibility FROM dbo.Summer_Project_Req"? If I can, I am not sure what type of control would be best to use or what syntax to use to write the code-behind. I would like the results to be displayed in a grid format. Thanks in advance for your help.

I'm trying to use the date() function in an openquery statement in query analyzer and I keep getting an illegal symbol ")" error. The statement is :
select *
from openquery([Big Blue], 'select cde_date, cde_item from acch1 where cde_date < date()')
The objective is to find records where cde_date is prior to today. The syntax works fine if I execute it on the mainframe in QMF and the ODBC connection works fine if I hard code the value. What I need is the ability to use the function so I can run the query on subsequent days without having to edit it.
Any suggestions??

Hello all,
Recently I changed over a ASP script from our old Access 97 database to our new SQL database. When I changed it over, some of my SQL pulls on my Active Server Page started to give me erros. One of them is the function
date(). When I used it pulling from Access like this :
strSQLQ = "SELECT * FROM cocoitem WHERE CustNum = '" & strcustnum & "' AND stat = 'C' AND [due-date] > DateAdd('yyyy', -1, Date()) Order By [cust-po], [due-date] ASC ;"
Then it worked fine. When I redirected the ASP to the new SQL server I recieved an error like this:
Microsoft OLE DB Provider for SQL Server error '80040e14'
'Date' is not a recognized function name.
/scripts/order/shippingstatsclose.asp, line 45
So my question is, what is the SQL server equivalent of the function Date()?

I have a challenge and am not very versed with coding this situation. The situation is breaking up an address into separate portions: number, number suffix, direction, street name, thoroughfare, street suffix, etc. I am having troubles getting started, could anyone point me somewhere in the right direction with a little guidance or has anyone done this and have the code stored? This is not my strong point and have been trying to improve, sorry. D--
