8Using the TSQL ShellThe TSQL Shell is one way to execute Transact-SQL code from Caché.To use the TSQL Shell, invoke the TSQLShell() method from the Caché Terminal as follows: DO$SYSTEM.SQL.TSQLShell(). This invokes the Caché SQL Shell and sets its DIALECT configuration parameter toMSSQL.You can perform the same operation by invoking the SQL Shell from the Caché Terminal as follows: DO$SYSTEM.SQL.Shell(), then setting the DIALECT configuration parameter. The SQL Shell supports three SETDIALECT options: MSSQL, Sybase, and Cache. For further details about this shell, refer to the “Using the SQL ShellInterface” chapter of Using Caché SQL.You can also execute Transact-SQL code as a Dynamic SQL program using the %Dialect property.Caché Transact-SQL (TSQL) Migration Guide 57
