I am using SQL Server 2005. I am having a peculiar need now.
I am having a Database and it in turn have several table(>50). All of these table have 开发者_JAVA技巧a similar named column with a condition. I want to query this column across all the tables in the DB.
I am not finding a proper solution in Googling. Please help me.
Thanks a lot in Advance :)
Maybe this can help you?
SELECT * FROM information_schema.tables
Afterwards, you can loop through all tables and query your column.
Using Kevin's suggestion you do something like this, then execute it's output.
DECLARE @ColumnName AS VARCHAR(20)
SET @ColumnName = 'MyColumn'
SELECT 'SELECT ' + @ColumnName + ' FROM ' + TABLE_NAME FROM information_schema.tables
sp_msforeachtable @command1=N'SELECT ''?'', * from ? WHERE yourcol=''whatever'''
Above will run query against every table in selected database, and print tablename + every column in the table for conditions met. If it reaches a table that has an invalid column, it'll just keep going (but print an error message).
