Create a Table variables schema from an existing table
Posted on 2003-10-30
I need to select some rows from a table in to a table variable. The problem I am having is that I need to define the schema for the table variable, which is essentailly the same as the table that I am selecting from. I was wondering if there was some other way of defining a table variables schema from a source, rather than hard coding it.
So something like
DECLARE @myTable table (SELECT * FROM tMyOtherTable)
would be nice
Also, using my table variable I then select a series of related data based on the pk.
So i'm doing
JOIN tBooleanValue ON tFieldValue.FieldValueID = tBooleanValue.FieldValueID
tFieldValue.ContainerID IN (SELECT ID FROM @myTable)
this several times. The only thing that changes is the tBooleanValue becomes tTextValue or tDateValue etc. I was wondering if there was some way I could put this in a loop and use an alias for the table that I want to select from.
