How to retrieve all row from all tables with where condition

Royce Roy153425-May-2015

I have a database and 10 tables in some tables I have a bit column named Open where I store a 0 if the record is not in use by an user and an 1 if the record is in use.

Well, I need to get all the records from all the tables in my database where the "open" column value is true, or 1.

Is this even possible to do?

Quick piece of code that gets list of tables within your database. Using a cursor loop through the answers checking it they have the fld named [open] and if it does the build a SQL statement and the execute this SQL string.

CREATE PROCEDURE usp_BulkTableOpenReport 
AS
BEGIN
 
    DECLARE @TBLS AS TABLE (REF INT IDENTITY (0,1), TABLENAME NVARCHAR(100), TABLEID BIGINT);
    DECLARE @TBL AS NVARCHAR(100);
    DECLARE @TBLID AS BIGINT;
    DECLARE @SQL AS NVARCHAR(MAX);
    DECLARE @I INT = 0;
    DECLARE @M INT = 0;
    DECLARE @V INT = 0
 
    INSERT INTO @TBLS(TABLENAME,TABLEID)
    SELECT NAME,OBJECT_ID FROM sys.tables
 
    SELECT @M = MAX(REF) FROM @TBLS
 
    WHILE @I <= @M
    BEGIN
        SELECT @TBL = TABLENAME, @TBLID= TABLEID FROM @TBLS WHERE REF = @I 
        /* CHECK TO MAKE INSURE THAT A FLD CALLED [OPEN] EXIST. */
        SELECT @V = COUNT(*) FROM SYS.columns WHERE name = 'OPEN' AND  OBJECT_ID = @TBLID
        IF @V != 0 
        BEGIN
            SET @SQL = 'SELECT * FROM [' + @TBL + '] WHERE [OPEN] = 1'
            EXEC SP_EXECUTESQL @SQL
        END;
        SET @I = @I + 1
    END; 
END
GO

From your c# application exec the query "EXEC usp_BulkTableOpenReport" then loop through the table outputs.
