Status: Open
Bug Type: ODBC related
Description: DB2 SQLColumns() doens't work by default.
After more research, please disregard this report.
the odbc_columns() is not working against DB2 7.1, but
there's something else going on. (It SIGSEGVs on multiple passes) I'll have to do
some more digging.
Apologies for the noise.

The workaround posted is incorrect as it'll change
the action of the cat/schema/table/etc values and
not the SIZE of the values.
Please ignore the workaround - the SQLColumns()
bugreport is still correct otherwise.

In ext/php_odbc.c function odbc_columns() has
an incorrect SQLColumns() set of parameters for
DB2 databases.
Currently:
rc = SQLColumns(result->stmt,
cat, SAFE_SQL_NTS(cat),
schema, SAFE_SQL_NTS(schema),
table, SAFE_SQL_NTS(table),
column, SAFE_SQL_NTS(column));
it should be something more along the lines of
rc = SQLColumns(result->stmt,
cat, 0,
schema, strnlen(schema),
table, strnlen(table),
column, strnlen(column));
DB2 Documentation link
http://nscpcw.physics.upenn.edu/db2_docs/db2l0/sqll1311.htm#HDRFNCOLN
Currently it follows the SQLColumns as described by the
MSDN, which says:
"If the SQL_ATTR_METADATA_ID statement attribute is set to SQL_TRUE, ColumnName is
treated as an identifier, and its case is not significant. If it is SQL_FALSE,
ColumnName is a pattern value argument; it is treated literally, and its case is
significant."
By default, DB2 has SQL_ATTR_METADATA_ID set to SQL_FALSE
and doesn't work with the current code. Can we get at least a check and warning
message for SQL_FALSE? I don't know about Oracle.
Workaround: set SQL_ATTR_METADATA_ID to SQL_TRUE
Thanks.
