Hello
I’m a beginer in libreoffice base.
I tried it for sorting a question bank.
I used wizard and made some columns for the table.
but in the last step I met an error: "firebird_sdbc error:
*Dynamic SQL Error
*SQL error code = -104
*Token unknown - line 1, column 243
*,
caused by
‘isc_dsql_prepare’

please help me.

*SQL error code = -104
*Token unknown - line 1, column 94
