function DatabaseSchema_mysql::buildTableNameCondition

Build a condition to match a table name against a standard information_schema.

MySQL uses databases like schemas rather than catalogs so when we build a condition to query the information_schema.tables, we set the default database as the schema unless specified otherwise, and exclude table_catalog from the condition criteria.
