sp_invalidate_textptr
Makes the specified in-row text pointer, or all in-row text pointers, in the transaction invalid. sp_invalidate_textptr can be used only on in-row text pointers, which are from tables with the text in row option enabled.
Syntax
sp_invalidate_textptr [ [ @TextPtrValue = ] textptr_value ]
Arguments
[ @TextPtrValue = ] textptr_value
Is the in-row text pointer that will be invalidated. textptr_value is varbinary(16), with a default of NULL. If NULL, sp_invalidate_textptr will invalidate all in-row text pointers in the transaction.
Return Code Values
0 (success) or 1 (failure)
Remarks
SQL Server allows a maximum of 1024 active valid in-row text pointers per transaction per database; however, a transaction spanning more than one database can have 1024 in-row text pointers in each database. sp_invalidate_textptr can be used to invalidate in-row text pointers and thus free up space for additional in-row text pointers.
For more information about the text in row option, see sp_tableoption.
