Hi, i have a little problem when selecting entries from a table, specified by a long match on a field of type TEXT. Is there a length limitation for the '=' operator when comparing a field of type TEXT to a given string ?
Example: SELECT description FROM sequences_33 WHERE description LIKE 'gi 17559974%'; Result: gi 17559974 ref NP_506864.1 (NM_074463) acid phosphatase [Caenorhabditis elega ns] gi 7499536 pir T21181 hypothetical protein F21A3.2 - Caenorhabditis elegans gi 3876155 emb CAB04153.1 (Z81509) predicted using Genefinder Similarity to As pergillus acid phosphatase (TR:Q12546) cDNA EST yk3g4.5 comes from this gene cDN A EST yk69f10.5 comes from this gene cDNA EST yk231b3.5 comes from this gene cDN A EST yk285e4.5 comes from this gene cDN (1 row) Thats ok. And now: SELECT description FROM sequences_33 WHERE description=' gi 17559974 ref NP_506864.1 (NM_074463) acid phosphatase [Caenorhabditis elega ns] gi 7499536 pir T21181 hypothetical protein F21A3.2 - Caenorhabditis elegans gi 3876155 emb CAB04153.1 (Z81509) predicted using Genefinder Similarity to As pergillus acid phosphatase (TR:Q12546) cDNA EST yk3g4.5 comes from this gene cDN A EST yk69f10.5 comes from this gene cDNA EST yk231b3.5 comes from this gene cDN A EST yk285e4.5 comes from this gene cDN' (0 row) The two strings are identical and there are no confusing characters in them. Any idea ? PS: The type of field description is TEXT Thanx in advance Michael ------------------------------------------------------------------------------- Dipl.-Inform.
