Does anybody know how SQLCOLUMNS is supposed to work? I have been trying every combination I could think of and all I ever get back is zero columns. When I use SQLTABLES, I get back the table information which I use in the SQLCOLUMNS at the appropiate positions. However, I still get back zero columns.
I am using two Oracle connections at the same time. One is version 11 and the other is 10.2;
Any guidance would be greatly appreciated. An example would be even better.
This is the snippet of code that I use successfully using SQLColumns with one open MySQL connection:
/* Obtain info for all columns */
call sayfile 'Obtain list of all columns for table 'tabellen.TABLE_NAME.i
kolommen. = ''
rc = SQLColumns('kolommen', t_q, t_o, tabellen.TABLE_NAME.i, t_t)
if rc < 0
then call terminate 'Failed to obtain list of columns for table "'tabellen.TABLE_NAME.i'" (rc = 'rc')'
call sayfile 'List of columns obtained for table "'tabellen.TABLE_NAME.i'"'
I have opned the connection and used SQLTables to obtain the list of tables which is parsed into tabellen.
I have struggled with the statement as well and what helped in my case was:
- t_q (table qualifier) and t_o (table_owner) set to '*'
- t_t (table type) set to 'TABLE'
- MySQL requires the table name to be specified and ny wildcards allowed. The documentation does not specify restrictions for Oracle.....
- do NOT specify a dot for the stem name! So 'kolommen' is correct but 'kolommen.' is not
Hope this helps. Ynze
