correct syntax for setting up a SQL string for CurrentDb.Execute

correct syntax for setting up a SQL string for CurrentDb.Execute

(OP)
I use the CurrentDb.Execute command quite often to launch a query within my DBA code but sometimes the
syntax doesn't exactly match the SQL of my query like in the following:

This works:

CODE -->

strSql = "delete * from SameOrd_tbl where License_PartNo is null"

    CurrentDb.Execute strSql 

This is totally wrong:

CODE -->

strSql = "Delete * FROM SameOrd_tbl WHERE (((SameOrd_tbl.License_PartNo)=" "))"

    CurrentDb.Execute strSql 

How do I fix the totally wrong?


Thanks

RE: correct syntax for setting up a SQL string for CurrentDb.Execute

i dont know you want to delete
try
strSql = "Delete * FROM SameOrd_tbl WHERE (((SameOrd_tbl.License_PartNo)=''))"
or
strSql = "Delete * FROM SameOrd_tbl WHERE (((SameOrd_tbl.License_PartNo)=' '))"

do you know what the difference between
1)null
2)empty string
3)space
is?

RE: correct syntax for setting up a SQL string for CurrentDb.Execute

If the field actually might contain a single space then try:

CODE --> VBA

strSql = "Delete * FROM SameOrd_tbl WHERE License_PartNo=' '" 

Or

CODE --> VBA

strSql = "Delete * FROM SameOrd_tbl WHERE License_PartNo="" """

How is the License_PartNo field defined in the table? A text? A number? Is NULL allowed?

Have fun.

Thanks Duane-

CODE -->

strSql = "Delete * FROM SameOrd_tbl WHERE License_PartNo=' '" 

This did the trick
