SQLDA Structure, Names Buffer, and Collation
Description
Eye-catcher value. Use this identifier to
initialize the eye_catcher field in the
SQLDA structure:
strncpy(sqlda.eye_catcher,
SQLDA_EYE_CATCHER,2);
where sqlda is the name of the SQLDA
structure.
The length in bytes of the SQLDA
structure header fields eye_catcher and
num_entries.
The length in bytes of one SQLVAR entry.
The overhead length in bytes added to the
names buffer. This overhead is the length
field (2 bytes), table name (8 bytes), and
