NULL textptr (text, ntext, or image pointer) passed to %ls function.

Error Message:
Msg 7133, Level 16, State 1, Line 5
NULL textptr (text, ntext, or image pointer) passed to %ls function.

Severity level:
16.

Description:
This error message appears when you try to pass a NULL pointer to the READTEXT or WRITETEXT function.

Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.

Resolution:
Errors of the Severity Level 16 are generated by the user and can be fixed by the SQL Server user. The statement cannot be executed this way. The pointer must have a valid value.

Versions:
All versions of SQL Server.

Example(s):
USE pubs
DECLARE @textpointer VARBINARY(16)
SELECT TEXTPTR(pr_info)
  FROM pub_info
READTEXT pub_info.pr_info @textpointer 1 25

Remarks:
In the above example we try to pass the variable @textpointer to the READTEXT function. Because the variable has only been declared but no value assigned to it, it contains a NULL and the error is raised.
