Is there anyway to change the data type of a variable while in an expression?
My problem is I am trying to compare a variable w/ a string data type to a variable w/ an object data type. I would change the data type of the variable from object to string but if I do that my sql task fails when it tries to write a value to that variable. The variable w/ the object data type is the result of an openquery sql stmnt. So I guess there are two ways around my problem.
1. Change data type of variable while in an expression..ie flow constriant
or
2. Change data type of vraiable from object to string and still get the openquery result to work.
I'm trying to compare 2 field in 2 different databases and one is varchar and one is numeric. Is there anyway I can tell SQL to treat the one thats numeric as varchar or convert numeric to varchar for the comparison string... I'm trying to run the following in query anaylzer:update crcwebauth.dbo.deviationmaster set ldate = (select max(qvdate) from crcbrio.dbo.invoice_tbl where dnumber = qvqote)It gives me error:Server: Msg 8114, Level 16, State 5, Line 1Error converting data type varchar to numeric.The DNumber field is numeric and the qvqote is a char field...
I received a db2 data file that I converted to MS-Access. From Access Iran the upsize wizard to put the tabel in SQL. It put the table in okbut all the data types are nvarchar. I have a couple of the fields thatare cureny and some that are numeric.I need to change the data types from nvarchar to numeric type fields. Iam new to SQL so I do not know all the commands. How do I change thedata type?Michael Charney*** Sent via Developersdex http://www.developersdex.com ***
How do I programatically change a column (say username) in a table (say tblusers) from varchar(25) to varchar(100)I am looking for something likealter tblusers set username as varchar(100) I know the above statement in nonsensical but it conveys the idea.
I'm doing a data conversion project, moving data from one SQL app toanother.I'm using INSERT INTO with Select and have the syntax correct. But whenexecuting the script I get:Server: Msg 8114, Level 16, State 5, Line 1Error converting data type varchar to float.Is it possible to change the data type during the INSERT INTO statement?Thanks
I've created a SQL View in SQL 2000 using a table that has columnsdefined as Numeric data type. In the view, I am grouping and summing.When I link the view via ODBC to Access, all of the data types arechanged to text. If I link the original table which the views arecreated from to Access, the data types are correct. So this problemobviously happens when I change the view to Group. Is there a wayaround this? I want the data types to be correct in Access when Ilink to the views.thanks,jim
I have tables (they are empty and there are no constraints) with columns typed as varchar. In a database I want to change the type of all the varchar columns in all the tables from varchar to nvarchar. What's the best way to do it? Can you suggest code?
I know that to get all the relevant columns I would issue a query like this
select * from information_schema.columns where data_type = 'varchar'
Then I would use a cursor... And that's exactly what I would not like to do. Is there any other way?
I am trying to extract certain data from MySQL (example sql statement is SELECT COLUMN1, COUNT(COLUMN2) FROM TABLE GROUP BY COLUMN1) and stored COLUMN1 and COUNT(COLUMN2) values into variables and then copy the values from the variables and insert them into a new table in sql server 2005 and has two columns in it (COLUMN1 of type nvarchar and COLUMN2 of type int). I can map the first output (COLUMN1) correctly to variable type String and store them in the new table in sql server 2005 (store the value in a variable type String and then use insert and store it into sql server using parameter in Execute Sql Task set the data type to NVARCHAR, but I cannot map the second output (COUNT(COLUMN2)) using the same method, I could not even get it to store into a variable of any type. Anyone have any idea how to go about it? Thanks in advance.
The output of the sql statement for MySQL should look like:
I have a table say Friend which has a column "IsSingle VARCHAR(10)" and this column has values like yes or No Now I want to change type of column IsSingle from VARCHAR to BIT, if I try to do it manaually SQL throws error that cannot convert yes to bit etc. I know that we can write a script to do this task but i dont know how ? Any pointers,links, suggestions will help me to start with.
I have a SQL update statement that updates some user names, however, the user names exceed the length of the data type. Currently, for the column username the data type is set to nvarchar (8).
How can I change that to nvarchar(10) in a SQL Update statement?
how to pass the numeric(12,0) data type to a variable in SSIS? what kind of variable data type should I choose? I am trying to assign object_key column ( numeric(12,0)) to a variable in SSIS
If i select int32 , it keep giving me an error: Error: 0xC001F009 at Row by Row process: The type of the value being assigned to variable "User::Object_Key" differs from the current variable type.

I have same table structures in two database and one master table which contains Table id, Table name,primary key, data type of primary key. i have to comapare Tables in both tha database and as per result i have to do insert,update or delete.
for that i have written query :
DECLARE @rowcount_mastertable FLOAT SET @rowcount_mastertable = (select count(*) from master_table)
SET @TABLE_NAME = (SELECT TABLE_NAME FROM MASTER_TABLE TABLE_ID = @COUNTER) SET @primary_key = (SELECT primary_key FROM MASTER_TABLE WHERE TABLE_ID = @COUNTER) SET @Primarykey_DATATYPE = (SELECT Primarykey_DATATYPE FROM MASTER_TABL WHERE TABLE_ID = @COUNTER)
--In below line i want to declare a variable and datatype should be same as what we got from master table so that i can use this @MAX_primary_key to fetch --max of primary key from table name where table id is 1 DECLARE @MAX_primary_key @Primarykey_DATATYPE SELECT @MAX_primary_key = MAX(@primary_key) FROM @TABLE_NAME WHERE TABLE_ID = @COUNTER
---But by running it i am getting error that "Incorrect syntax near '@Primarykey_DATATYPE'. and "Must declare the variable '@MAX_primary_key'.
I am using SQL Server 2000 Enterprise Edition fully patched. Database is in Simple Recovery mode.
I need to change a column's data type from "int(4)" to "smallint(2)". I know for sure that there will be no data (precision) lost, because I know the possible values that this column could have.
My problem is that the table I am dealing with has 600,000,000 records in it. I dropped all indexes before I tried to alter the table. But still it is taking forever and filling up my 280GB disk with transaction log file.
I know that in Oracle, if I want I can turn off logging and do these kind of modifications relatively faster.
I was wondering if there is a way of disabling logging before running this alter command.
What is the best practice to handle a situation of this sort?
Ilve install sql server 2012 in my pc and i want to change datetime default format. How can i do this and please i dont want to take the result from select convert() or select cast or something like this. I ve want to take the format i want writing query select datecolumn from table.Â

Is any way to convert automaticaly by select only column? or can i change at all once? or must write function to when i select the column can change automatic ? or another thing, i ve see in column properties something like formula. In computed column specification in formula i wrote this:Â
And I take the format i want automaticaly but i get the current date for all rows and i cant edit or insert that column anymore. So, how to change the format of date time but no from select query.
In a stored proc, can you declare a local variable that is an existing column in a table & then based on other criteria, do an order by using the local variable?
Can we retrieve data from table type variable as an array in oracle key values..
E.g.
ALTER PROCEDURE prn1( @p_prn as KeyValuePair readonly) -- proc which having parameter table type as parameter AS declare @v_formatted_str varchar(50) BEGIN set @v_formatted_str = v_formatted_str + @p_prn(1)(1) END
I am trying to find what datatype I can use for variable values like below in a column
E.g. column which we get
10000.10 100 180.34 98203710231.34
From the above example, you can see some of the values contains no decimal and with decimal
Also we cant say whether the decimal comes after the 5th number or 10th number. Any other datatype to capture this values. If not last option is to give varchar2.

I need to update a large table, about 55 million rows, without filling the transaction log, in the shortest time as possible. The goal is to alter the table and change the data type for Text column from VARCHAR(7900) to NVARCHAR(MAX).
Since I cannot do it with an ALTER TABLE statement (it would fill up the transaction log) I'm thinking to:
- rename column Text in Text_OLD - add Text column of type NVARCHAR(MAX) - copy values in batches from Text_OLD to Text
The table is defined like:
create table DATATEXT( rID INTEGER NOT NULL, sID INTEGER NOT NULL, pID INTEGER NOT NULL, cID INTEGER NOT NULL, err TINYINT NOT NULL,
[Code] ....
I've thought about a stored procedure doing this but how to copy values in batch from Text_OLD to Text.
The code I would start with (doing just this part) is the following, but maybe there are more efficient ways to do it, or at least there's a better way to select @startSeq in the WHILE loop (avoiding to select a bunch of 100000 sequences and later selecting the max).
declare @startSeq timestamp declare @lastSeq timestamp select @lastSeq = MAX(sequence) from [DATATEXT] where [Text] is null select @startSeq = MIN(Sequence) FROM [DATATEXT] where [Text]is null BEGIN TRANSACTION T1 WHILE @startSeq < @lastSeq
Hello Everyone,A have a Managed Stored Procedure ([Microsoft.SqlServer.SqlProcedure]). In it I would like to call a UserDefinedFunction:public static SqlInt32 IsGetSqlInt32Null(SqlDataReader dr, Int32 index) { if(dr.GetSqlValue(index) == null) return SqlInt32.Null; else return dr.GetSqlInt32(index) }I than allways get the following ErrorMessage:Column, parameter, or variable #1: Cannot find data type SqlDatareader.Is it not possibel to pass the SqlDatareader to a SqlFunction, do the reading there and return the result.My original Problem is, that datareader.GetSqlInt32(3) throws an error in case there is Null in the DB. I thought SqlInt32 would allow Null.Would appreciate any kind of help! Thanks

I am creating a customer data flow component for SSIS for use in a package. I've got some custom properties that I am exposing using the supplied advanced editor (no custom property editor here).
Some of my properties are enumerated types, and I have deciphered how to get those properties to show as dropdown lists of their respective enumerations. (For those of you who may be looking as hard as I did as to how to accomplish this, see the end of this post.)
I also have a few properties which request SSIS package variable names - such as an file name variable. However, I can't figure out how to tell the advanced editor that the property is looking for an SSIS variable, so that it can show a dropdown list of package variables, much like virtually any other Microsoft supplied Data Flow component can.
Is there a Type Converter I could specify for those custom properties? Is there another way to instruct SSIS that my custom property is expecting a variable? Or do I need to code a custom UI for editing my Data Flow Task?
To create a dropdown list of values for a custom property that represents an enum, do the following:
1. Create your enum definition, such as "public enum ThisIsMyEnum { one, two }"
2. Create a new class that inherits from TypeConverter, such as "public class MyEnumConverter : TypeConverter"
3. Override "CanConvertFrom", and return true if "sourceType == typeof(string)"
4. Override "CanConvertTo", and return true if "destinationType == typeof(string)"
5. Override "ConvertFrom", and return the enum value (such as "one" or "two" in my example) that corresponds to the string passed in the parameter "value"
6. Override "ConvertTo", and return a string that corresponds to the enum value passed in the parameter "value"
7. Override "GetStandardValuesSupported" and return true
8. Override "GetStandarValuesExclusive" and return true to indicate that ONLY the enum values should be accepted
9. Override "GetStandardValues", and return a new StandardValuesCollection constructed with Enum.GetValues() of your enum, such as "return new StandardValuesCollection(Enum.GetValues(typeof(ThisIsMyEnum)));"
10. Just above your "public enum" declaration, add a "TypeConverter" attribute to link your type converter to your enum, such as "[TypeConverter(typeof(MyEnumConverter))]"
11. In "ProvideComponentProperties", after you've created your custom property like this: "IDTSCustomProperty90 propEnum = ComponentMetaData.CustomPropertyCollection.New()", add another line to specify the TypeConverter property of the property to the full assembly name of your type converter, like so: "propEnum.TypeConverter = typeof(MyEnumConverter).AssemblyQualifiedName;"
Is there a way to change an image data type? I want to make a change to some deployed SQL 2008 SSIS deployed packages. I have a TSQL SELECT that searches the packages for a string. But I would like to be able to change a string. I have googled it but cannot find anything.
Does abyone know how to compare data-type xml in a temp/variable/physical table in MSSQL 2000?
I tried this works in MSSQL 2005,
Code Snippet create Table #t1 ([c1] int identity(1,1) not null, [c2] text) create Table #t2 ([c1] int identity(1,1) not null, [c2] text) Insert into #t1 Values('This is a test') Insert into #t2 Values('This is a test') Select * from #t1 Select * from #t2 Select * from #t1 where [c2] LIKE (Select [c2] from #t2) drop table #t1 drop table #t2
but not MSSQL 2000.
Server: Msg 279, Level 16, State 3, Line 12 The text, ntext, and image data types are invalid in this subquery or aggregate expression.
Is this true (from BOL)?
Code SnippetIn comparing these column values, if any of the columns to be compared are of type text, ntext, or image, FOR XML assumes that values are different (although they may be the same because Microsoft® SQL Server„¢ 2000 does not support comparing large objects); and elements are added to the result for each row selected.
I'm working on an SSIS package that uses a vb.net script to grab some XML from a webservice (I'd explain why I'm not using a web service task here, but I'd just get angry), and I wish to then assign the XML string to a package variable which then gets sent along to a DataFlow Task that contains an XML Source that points at said variable. when I copy the XML string into the variable value in the script, if do a quickwatch on the variable (as in Dts.Variable("MyXML").value) it looks as though the new value has been copied to the variable, but when I step out of that task and look at the package explorer the variable is its original value.
I think the problem is that the dataflow XML source has a lock on the variable and so the script task isn't affecting it. Does anyone have any experience with this kind of problem, or know a workaround?
I have an SSIS package that creates a csv file based on a execute sql task.
The sql is incredibly simple select singlecolumn from table.
In the properties of the execute sql task I specify the result set as "full result set" when I run it I get the error that: Error:
The type of the value being assigned to variable "User::CSVoutput" differs from the current variable type.
Variables may not change type during execution. Variable types are strict, except for variables of type Object.
If I change the resultset to single row then I only get the first row from the DB (same if I choose none), If I choose XML then I get the error that the result is not xml. What resultset type do I need to choose in order to get all the rows into the CSV? The variable I am populating is of type string and is User::CSVoutput
Hi all,I have a table called PTRANS with few columns (see create script below).I have created a view on top that this table VwTransaction (See below)I can now run this query without a problem:select * from dbo.VwTransactionwhereAssetNumber = '101001' andTransactionDate <= '7/1/2003'But when I create an index on the PTRANS table using the command below:CREATE INDEX IDX_PTRANS_CHL# ON PTRANS(CHL#)The same query that ran fine before, fails with the error:Server: Msg 242, Level 16, State 3, Line 1The conversion of a char data type to a datetime data type resulted inan out-of-range datetime value.I can run the same query by commeting out the AssetNumber clause and itworks fine. I can also run the query commenting out the TransactionDatecolumn and it works fine. But when I have both the conditions in theWHERE clause, it gives me this error.
