Underscore CLI/ODBC configuration keyword

This keyword specifies if the underscore character '_' will be recognized as a wildcard or only as the underscore character. The possible settings are as follows:

• 0 - The underscore character is treated only as the underscore character.
• 1 - The underscore character is treated as a wildcard that matches any single character, including no character.

Setting Underscore to 0 can improve performance when there are database objects with names that contain underscores.

This keyword applies only to the following catalog functions that accept search patterns as arguments:

• SQLColumnPrivileges()
• SQLColumns()
• SQLProcedureColumns()
• SQLProcedures()
• SQLTablePrivileges()
• SQLTables()

Note that catalog functions may only accept search patterns on particular arguments. Refer to the documentation of the specific function for details.
