Question

Here goes, second post, first didn’t go to well….

I am calling an SP from a Gridview in ASP. I pass in a table name as a variable along with some other variables. I need to UPDATE my original table that the Gridview attaches to but also build a Datalist, I have used a Fetch and got it working fine. Cycle through those records and INSERT data into third table. I was told (in first post) I need to build the SQL string first then execute it. when I write it that way the second part of the insert does not work.

Here is the code in its sliced up form because of efforts to find a succesfull structure….

    @currTable varchar(100),
    @ID int,
    @short_Text varchar(250),
    @brief_Descrip varchar(250) = Null,
    @needsTranslation varchar(10) = Null,
    @prev_LangString varchar(250) = Null,
    @lang_String varchar(250) = Null,
    @original_lang_String varchar(250) = Null,
    @StringID_from_Master varchar(250),     
    @GUID varchar(250) = Null

/*

*/

AS        
SET NOCOUNT ON;

DECLARE @userTable AS VARCHAR(200);
SET @userTable = @currTable
DECLARE @submitDate1 DATETIME;
SET @submitDate1 = GETDATE()



SET @prev_LangString = @original_lang_String
SET @needsTranslation = 'false'

DECLARE @sql varchar(max)
    -- Establish update to the language tabel of user and prepare to search DB for all strings that will need to be updated.
BEGIN

--  DECLARE @sql nvarchar(4000)
SELECT @sql = ' UPDATE  ' + @currTable + 
              ' SET [lang_String] = ' + @lang_String + 
              ' WHERE (ID = ' + @ID + ' ';

EXEC sp_executesql @sql, N'@ID nvarchar(10)', @ID                


        --  UPDATE       @userTable
        --  SET                [lang_String] = @lang_String, [date_Changed] = @submitDate1, [prev_LangString] = @prev_LangString, [needsTranslation] = @needsTranslation, [brief_Descrip] =  @brief_Descrip
        --  WHERE        (ID = @ID)

END

BEGIN               
    DECLARE usedIN_DBScursor CURSOR
    FOR
    SELECT       tblUniquetblStringsMaster_ID, Database_Name, dbKeyID_ofStringName
    FROM         tblDBUsage
    WHERE        (tblUniquetblStringsMaster_ID = @StringID_from_Master );


                -- Declare the variables to store the values returned by FETCH.
    DECLARE @tblUniquetblStringsMaster_ID AS INT;
    DECLARE @dbKEYID as INT;
    DECLARE @dbName as varchar(100);

    OPEN usedIN_DBScursor;

    -- Perform the first fetch and store the values in variables.
    -- Note: The variables are in the same order as the columns
    -- in the SELECT statement. 

    FETCH NEXT FROM usedIN_DBScursor
    INTO @tblUniquetblStringsMaster_ID, @dbName, @dbKEYID;

    -- Check @@FETCH_STATUS to see if there are any more rows to fetch.
    WHILE @@FETCH_STATUS = 0
    BEGIN
    -- Update pending strings table with translation.           
        BEGIN
            INSERT INTO tblPendingDBUpdates
                                     (stringMasterID, databaseName, databaseStringID, englishText, foreignLangText, submitDate, GUID)
            VALUES        (@StringID_from_Master, @dbName, @dbKEYID, @short_Text, @lang_String, @submitDate1, @GUID);                                       
        END 
--      SET @sql = ''
    -- This is executed as long as the previous fetch succeeds.
        FETCH NEXT FROM usedIN_DBScursor
        INTO @tblUniquetblStringsMaster_ID, @dbName, @dbKEYID;
    END

    CLOSE usedIN_DBScursor;
    DEALLOCATE usedIN_DBScursor;    

END

It seems that your procedure could be re-written as follows:

ALTER PROCEDURE dbo.procedure_name
    @currTable varchar(100),
    @ID int,
    @short_Text varchar(250),
    @brief_Descrip varchar(250) = Null,
    @needsTranslation varchar(10) = Null,
    @prev_LangString varchar(250) = Null,
    @lang_String varchar(250) = Null,
    @original_lang_String varchar(250) = Null,
    @StringID_from_Master varchar(250),     
    @GUID varchar(250) = Null
AS
BEGIN
    SET NOCOUNT ON;

    DECLARE @sql NVARCHAR(MAX);

    SELECT @sql = N' UPDATE  ' + QUOTENAME(@currTable) + ' SET [lang_String] = ''' 
        + REPLACE(@lang_String,'''','''''') + ''' WHERE ID = ' + RTRIM(@ID) + ';';

    EXEC sp_executesql @sql;

    INSERT tblPendingDBUpdates
    (
      stringMasterID, 
      databaseName,
      databaseStringID,
      englishText,
      foreignLangText,
      submitDate,
      [GUID]
    )
    SELECT
      @StringID_from_Master,
      Database_Name,
      dbKeyID_ofStringName,
      @short_Text,
      @lang_String,
      @submitDate1,
      @GUID
    FROM
      tblDBUsage
      WHERE tblUniquetblStringsMaster_ID = @StringID_from_Master;
END 
GO

However, I am not sure why you need a cursor in your original version, or what you mean by “does not work.” Can you explain?
