cd $CAT_DIR
mysql -e 'create database DBGlobal'
mysql -e 'create database DC3a_DB'
mysql -D DC3a_DB < sql/lsstSchema4mysqlDC3a.sql
mysql -D DBGlobal < sql/setup_DB_global.sql
mysql -D DC3a_DB < sql/setup_storedFunctions.sql
mysql -D DC3a_DB < sql/setup_perRunTables.sql
mysql -D DC3a_DB < sql/setup_sdqa.sql
