Hello everyone,

I have a script checking and creating a HASH TABLE

SQL

IF EXISTS (SELECT keyid FROM #temp)
BEGIN
DROP TABLE #temp
END

SELECT * INTO #temp FROM [TABLE]
WHERE ID = 1593366

This works fine Microsoft SQL Server Management Studio, but when I try using this in my VB.NET Project, a runtime occur Invalid object name'#temp'. I even try this

SQL

IF EXISTS (SELECT keyid FROM #temp)
BEGIN
DROP TABLE #temp
END

but same happens

This is my code

VB

If SQLConn.State = ConnectionState.Closed Then SQLConn.Open()
Dim SQLCmd As New SqlCommand
SQLCmd.Connection = SQLConn
SQLCmd.CommandText = SQL
SQLCmd.ExecuteNonQuery()

Please help, Thanks

what value SQL holds at line SQLCmd.CommandText = SQL?

Since a temp table is local to the context, there couldn't possibly be a temp table at the point in the code where you have the IF EXISTS(SELECT...) and DROP TABLE statements.

I do not understand why you need to create a temp table.
Why not use just SELECT * FROM [TABLE] WHERE ID = 1593366 in your VB .NET project?

Also, your first example fails in SQL Server Management Studio 2012 with the error:
Msg 208, Level 16, State 0, Line 1
Invalid object name '#temp'.

I just do this and it works
SELECT * INTO temp FROM [TABLE]
WHERE ID = 1593366
This code is just the first script in my SQL and theres a lot more
