Hello every body.
First of all sorry for my bad english but I'm french ;-)
My internship consits into making a generic table exporter (with a table list). Export into csv files.
I have tried 2 solutions :
1 - Create a DTS with a Dynamic Properties Task. The problem is I can easily change the destination file but when I change the table source I don't know how to remap the transformations between source and destination (do you see what I mean ?). Any idea ?
2 - Use the bcp command. Very simple but how to do when tables contains the separator caracter ? for example : If a table line is "toto" | "I am , very happy" --> the csv file will look like this : toto, I am , very happy --> problem to get back the data ( to much comma ).
Does someone has a solution ?
Last point is how to export the table structure ? For the moment, using the table structure, I generate an sql query which creates a table (I write this query in a file). Isn't there any "cleaner" solution ?
I want to use ONE stored procedure to update/insert about 300 tables in a database. I hoped this code would work but it gives me an error:
ALTER PROCEDURE [dbo].[InsertRowsTick] @tableName varchar, @bid float, @ask float, @last float, @volume int, @dateTimed DateTime AS BEGIN SET NOCOUNT ON; INSERT INTO tableName ( bid, ask, last, volume, dateTimed) Values ( @bid, @ask, @last, @volume, @dateTimed) END
When I (1) commented out @tableName parameter and (2) instead of INSERT INTO tableName wrote: INSERT INTO <realtableName> the code (C#) executed and the table was filled.
How can I use a generic table name as a parameter?
In general (I know.. lots of factors) but in general will adding more RAM to a SQL box help the performance? I'm working w/ 256MB right now, and deciding whether to add 256MB or 512MB? Any advice
Thanks and sorry so generic but this is a vendored app and they know of design issues but for now that can't be changed.
This Audit Trigger is Generic (i.e. non-"Table Specific") attach it to any tabel and it should work. Be sure and create the 'Audit' table first though.
The following code write audit entries to a Table called 'Audit' with columns 'ActionType' //varchar 'TableName' //varchar 'PK' //varchar 'FieldName' //varchar 'OldValue' //varchar 'NewValue' //varchar 'ChangeDateTime' //datetime 'ChangeBy' //varchar
using System; using System.Data; using System.Data.SqlClient; using Microsoft.SqlServer.Server;
public partial class Triggers { //A Generic Trigger for Insert, Update and Delete Actions on any Table [Microsoft.SqlServer.Server.SqlTrigger(Name = "AuditTrigger", Event = "FOR INSERT, UPDATE, DELETE")]
public static void AuditTrigger() { SqlTriggerContext tcontext = SqlContext.TriggerContext; //Trigger Context string TName; //Where we store the Altered Table's Name string User; //Where we will store the Database Username DataRow iRow; //DataRow to hold the inserted values DataRow dRow; //DataRow to how the deleted/overwritten values DataRow aRow; //Audit DataRow to build our Audit entry with string PKString; //Will temporarily store the Primary Key Column Names and Values here using (SqlConnection conn = new SqlConnection("context connection=true"))//Our Connection { conn.Open();//Open the Connection //Build the AuditAdapter and Mathcing Table SqlDataAdapter AuditAdapter = new SqlDataAdapter("SELECT * FROM Audit WHERE 1=0", conn); DataTable AuditTable = new DataTable(); AuditAdapter.FillSchema(AuditTable, SchemaType.Source); SqlCommandBuilder AuditCommandBuilder = new SqlCommandBuilder(AuditAdapter);//Populates the Insert command for us //Get the inserted values SqlDataAdapter Loader = new SqlDataAdapter("SELECT * from INSERTED", conn); DataTable inserted = new DataTable(); Loader.Fill(inserted); //Get the deleted and/or overwritten values Loader.SelectCommand.CommandText = "SELECT * from DELETED"; DataTable deleted = new DataTable(); Loader.Fill(deleted); //Retrieve the Name of the Table that currently has a lock from the executing command(i.e. the one that caused this trigger to fire) SqlCommand cmd = new SqlCommand("SELECT object_name(resource_associated_entity_id) FROM ys.dm_tran_locks WHERE request_session_id = @@spid and resource_type = 'OBJECT'", conn); TName = cmd.ExecuteScalar().ToString(); //Retrieve the UserName of the current Database User SqlCommand curUserCommand = new SqlCommand("SELECT system_user", conn); User = curUserCommand.ExecuteScalar().ToString(); //Adapted the following command from a T-SQL audit trigger by Nigel Rivett //http://www.nigelrivett.net/AuditTrailTrigger.html SqlDataAdapter PKTableAdapter = new SqlDataAdapter(@"SELECT c.COLUMN_NAME from INFORMATION_SCHEMA.TABLE_CONSTRAINTS pk , INFORMATION_SCHEMA.KEY_COLUMN_USAGE c where pk.TABLE_NAME = '" + TName + @"' and CONSTRAINT_TYPE = 'PRIMARY KEY' and c.TABLE_NAME = pk.TABLE_NAME and c.CONSTRAINT_NAME = pk.CONSTRAINT_NAME", conn); DataTable PKTable = new DataTable(); PKTableAdapter.Fill(PKTable);
switch (tcontext.TriggerAction)//Switch on the Action occuring on the Table { case TriggerAction.Update: iRow = inserted.Rows[0];//Get the inserted values in row form dRow = deleted.Rows[0];//Get the overwritten values in row form PKString = PKStringBuilder(PKTable, iRow);//the the Primary Keys and There values as a string foreach (DataColumn column in inserted.Columns)//Walk through all possible Table Columns { if (!iRow[column.Ordinal].Equals(dRow[column.Ordinal]))//If value changed { //Build an Audit Entry aRow = AuditTable.NewRow(); aRow["ActionType"] = "U";//U for Update aRow["TableName"] = TName; aRow["PK"] = PKString; aRow["FieldName"] = column.ColumnName; aRow["OldValue"] = dRow[column.Ordinal].ToString(); aRow["NewValue"] = iRow[column.Ordinal].ToString(); aRow["ChangeDateTime"] = DateTime.Now.ToString(); aRow["ChangedBy"] = User; AuditTable.Rows.InsertAt(aRow, 0);//Insert the entry } } break; case TriggerAction.Insert: iRow = inserted.Rows[0]; PKString = PKStringBuilder(PKTable, iRow); foreach (DataColumn column in inserted.Columns) { //Build an Audit Entry aRow = AuditTable.NewRow(); aRow["ActionType"] = "I";//I for Insert aRow["TableName"] = TName; aRow["PK"] = PKString; aRow["FieldName"] = column.ColumnName; aRow["OldValue"] = null; aRow["NewValue"] = iRow[column.Ordinal].ToString(); aRow["ChangeDateTime"] = DateTime.Now.ToString(); aRow["ChangedBy"] = User; AuditTable.Rows.InsertAt(aRow, 0);//Insert the Entry } break; case TriggerAction.Delete: dRow = deleted.Rows[0]; PKString = PKStringBuilder(PKTable, dRow); foreach (DataColumn column in inserted.Columns) { //Build and Audit Entry aRow = AuditTable.NewRow(); aRow["ActionType"] = "D";//D for Delete aRow["TableName"] = TName; aRow["PK"] = PKString; aRow["FieldName"] = column.ColumnName; aRow["OldValue"] = dRow[column.Ordinal].ToString(); aRow["NewValue"] = null; aRow["ChangeDateTime"] = DateTime.Now.ToString(); aRow["ChangedBy"] = User; AuditTable.Rows.InsertAt(aRow, 0);//Insert the Entry } break; default: //Do Nothing break; } AuditAdapter.Update(AuditTable);//Write all Audit Entries back to AuditTable conn.Close(); //Close the Connection } }
//Helper function that takes a Table of the Primary Key Column Names and the modified rows Values //and builds a string of the form "<PKColumn1Name=Value1>,PKColumn2Name=Value2>,......" public static string PKStringBuilder(DataTable primaryKeysTable, DataRow valuesDataRow) { string temp = String.Empty; foreach (DataRow kColumn in primaryKeysTable.Rows)//for all Primary Keys of the Table that is being changed { temp = String.Concat(temp, String.Concat("<", kColumn[0].ToString(), "=", valuesDataRow[kColumn[0].ToString)].ToString(), ">,")); } return temp; } }
The trick was getting the Table Name and the Primary Key Columns. I hope this code is found useful.
Hi All, I have a Problem while updating one table data from another table's data using sql server 2000. I have 2 tables named TableA(PID,SID,MinForms) , TableB(PID,SID,MinForms) I need to update TableA with TableB's data using a single query that i have including in a stored procedure.
I want to be able to query with a start date(@start) and then calculate 1 year from there. I figured since the date is of type integer just add 364 and it will give me the day before 1 year. So if its 1998-05-01, Id get 1999-04-31.
Here's the scenario: whenever a change (insert/update/delete) has occured in any of the tables, it needs to be logged by adding the changed table's name, and changed columns' names (if any) into the special ChangeLog table. So, is it possible for me to write a generic trigger that would get the name of the table it just executed upon and names of every column affected by the UPDATE and then insert those into the Log table? If this is not possible, how do you suggest it should be done?
I'm familiar with standard SQL but T-SQL is completely new to me, so please bear with me if my question makes no sense...
How to disappear the generic bar in the report, or to disappear some options (example export). I speak about the bar which in the top of the report or there are the numbers of pages.
Hello,I have a DataSet which results from accessing an SQL database.Each row is an Article and has various columns like Title, Description, etc.I have created a Generic List as follows:Dim Articles As Generic.List(Of Article)Article is a class with various properties. Each property is the same as each column in the dataset.I want to fill the Generic List with the data from my DataSet.How can I do this?Thanks,Miguel
Hello, Can someone please guide me to online resources or books on how to design generic database? I mean, I can have a "Record" that can have a set of fixed fields like: ID, Title, CreatedOn, etc ... and I can add as many properties I want to that record in a vertical way. Then based on the generic tables present, I can fit in the same table, a Record for Customer, a Record for House, a Record for Order. All share the same set of Fields, but each has its own set of proeprties. This way, I design my database once, and customize it to fit any type of applications I need. Is there something like that or just dreaming? thanks
I have 24 lookup tables that contain the same columns (e.g. Rec_Id (identity field), Code, Desc) and I need to build an interface for each of these tables with Create, Update, and Delete capabilities.
I would like to create three stored procedures (create, update, delete) that would perform the task for any of the lookup tables.
For example, table AGENCY has three fields (Agency_id (identity field), Agency_Code, Agency_Desc) and I need to add a new record to AGENCY. I would like to call a stored procedure that would take the parameters @tablename, @code, @desc, and then create a new record in the table specified by @tablename.
I could then use a single "create" stored procedure for all of the lookup tables when adding a new record, rather than creating a separate "create" stored proc for each of my lookup tables.
I am attempting to create a generic stored procedure in SQL Server 6.5 which returns a record count of a specific table passed in as a parameter. The stored procedure looks like this"
CREATE PROCEDURE asp_GetRecordCount @tablename varchar(30), @recordcount integer OUTPUT AS /* Generic stored procedure which returns number of records in a table. */ SELECT @recordcount = COUNT(*) FROM @tablename RETURN GO
The problem is that when I save the stored procedure, SQL Server balks at the FROM @tablename entry. Any suggestions? Thanks.
My current project requires me to convert a mysql based software to a more generic one. I started by designing separate db class files and separated the lower level connection queries from the business logic. By doing this, I now have mssql.class, mysql.class, sqllite.class etc..
But am not sure how to handle sql functions in queries. For instance, one of my queries need the use of a date function to add minutes to a db field.
In mysql, I accomplish this using
dbfield+interval '$arg' minute between date1 and date1
But in mssql I cannot use this type of query. It seems I'll have to use date_add() function. How do I handle this situation?
I have a bunch of tables for my basketball club's d/b. I want to be able to interrogate them to build a web page showing player stats. For example, I want a table showing the top 5 scorers, top 5 3-point scorers, etc. What's got me foxed is how to join it all up and then sort it into the top 5 order. The main tables in question are T_Member, T_Fixture, T_Season and T_FixtureTeam:
Where you see the same field name, that field data is common for all tables that it appears in. In other words, for example, the T_FixtureTeam 'FixtureNo' and 'MemberNo' fields are made up of 'T_Fixture.FixtureNo' and 'T_Member.MemberNo' respectively.
Ready? The user will select a season at the top of the page (although there's a default to the current season (CurrentSeason is a Boolean field). The query needs to: - Find all fixtures in that season - Find all members who played in those fixtures - Find the top 5 3-point scorers (or whatever stat I'm gathering) for those matches - Sort the resulting data
I figure I need a JOIN on MemberNo but, as I say, the rest of it has my head spinning.
I'm receiving "a generic error occurred in gdi+" processing error while running a preview of my report inside visual studio. When this report is opened by a client, their browser will just hang (Not Responding).
Other reports don't have error. The report will not render any chart although thousands of record will be need to output.
We want our database to be unicode complaint and i need a generic collation that should do the work irrespective of the fact what data is entered in the database. Can someone suggest me any generic collation for that.
Hey I'm using this DAL to populate a generic list called assetDetailListHowever I'm adding a 2nd result set to my stored proc, protected void GenerateAssetDetails<T>(DbDataReader dataReader, ref List<AssetDetails> assetDetailList) { while (dataReader.Read()) { // Create a new culture AssetDetails assetDetail = new AssetDetails(); // Set the culture properties assetDetail.FileName = dataReader.GetString(dataReader.GetOrdinal("filename")); assetDetail.Title = dataReader.GetString(dataReader.GetOrdinal("title")); assetDetail.AltTag = dataReader.GetString(dataReader.GetOrdinal("alt_tag")); assetDetailList.Add(assetDetail); dataReader.NextResult();// this is the 2nd result set AssetContent assetContent = new AssetContent(); assetContent.content_id = dataReader.GetInt32(dataReader.GetOrdinal("content_id")); how do I creatre another list .Add(assetContent); } // Close and dispose of the reader dataReader.Close(); dataReader.Dispose(); } #endregion }
I€™ve got a few Script Task in my dtsx. Up to the moment I don€™t need have generic functions but I was wondering if it is possible to use a such functions. I attach you a sample of I say you:
Here is my situation. I have a fairly large query that I am working on in visual studio (data tab). I am at the point where the program will NOT let me type (add SQL code) anymore. I found that clicking the Generic Query Designer (turning the query builder on) button switches the format then allows me to add more code. Well, this solves the running out of room issue, BUT now it does something to my code and it will not process it. Prior to clicking the Generic Query Designer button, everything worked w/ no errors. I did not change anything, but simply pressed the Generic Query Designer button (turning the query builder on) and now it dose not work now. Just for kicks, I have pasted my working origional code into SSMS, added code and it executed just fine in SSMS. But then I pasted back into visual studio and it gave me the same errors?
Has anyone experienced this? Is there a maximum for lines of code? Why does the Generic Query Designer (having query builder on) change my code? All comments are welcome!
An SSIS package to transfer data from a DB instance on SQL Server 2005 to SQL Server 2000 is extremely slow. The package uses an OLEDB Source to OLEDB Destination for data transfer which is basically one table from sql server 2005 to sql server 2000. The job takes 5 minutes to transfer about 400 rows at night when there is very little activity on the server. During the day the job almost always times out.
On SQL Server 200 instances the job ran in minutes in the old 2000 package.
Is there an alternative to this. Tranfer Objects task does not work as there is apparently a defect according to Microsoft. Please let me know if there is any other option other than using a Execute 2000 package task or using an ActiveX Script to read records from one source and to insert them into the destination source, which I am not certain how long it might take and how viable will that be?
How can I get the table sizes for data and transaction logs just like we had in SQL Server 7.0 on the first screen of the Entreprise Manager?
I remember having a bar showing used space in blue and unused in magenta. I bet there are a couple of functions that can be added in a script that will retreive this info.

sql server 2000I am currently maintaining a table that contains 30 Million+ records,30 columns, and 11 indexes and will double within the next six mouths.The application that accesses this table, mainly for read onlypurposes, runs without any problems. We have begun using Crystalreports and are now having problems. When we create reports thataccesses the large table our server has significant performance dip.The application begins to time out and the reports take a very longtime, even with simple selects on indexed field.I have began looking into partitioning the large table on its key fieldand creating a partition view. But from what I have read this willonly help if we key on the partitioned field. And all other searcheswill actually take a little longer.Archiving old data is not an option. All the data is being usedAny suggestions will be appreciated. Thanks in advance.Rick
Unfortunately a table is Deleted by me from my database. Now How I can Recover that I have no data and structure of that table Now. It Was Very IMP. Table . So Plz Help.......

Then Created the partitioned View using below script CREATE VIEW V AS SELECT * FROM T1 UNION ALL SELECT * FROM T2
I am able to insert the US records using view insert into V values (1,'us')
Problem: I am not able to insert the non US records like UK and JN... It is thorwing the exception like partition column not find. eg : insert into V values (1,'uk')
PLease help me to insert the non US records into the View
