Purpose

Configure SQL statement syntax


Syntax

SET SQLDIALECT TO RECITAL | VFP | MYSQL


See Also

SET PAUSE, SET SQL, SQL


Description

Where Recital, MySQL and VFP differ in their SQL syntax, the SET SQLDIALECT command can be used to select the syntax to be used.

By default, SET SQLDIALECT is set to RECITAL. Since the SET SQLDIALECT setting affects program compilation, it should be set prior to compilation rather than in a program itself, for example in a config.db configuration file.

;

The semi-colon, ’;’, is used to terminate SQL statements when SQLDIALECT is set to RECITAL or MYSQL. It is used as a line continuation character when SQLDIALECT is set to VFP.

EXEC SQL

When SQLDIALECT is set to RECITAL, SQL statements embedded in programs must be preceded by the EXEC SQL statement unless SET SQL is ON. Note: No longer required in Recital 10.

.sql programs

When a program with a ’.sql’ file extension is run, SQLDIALECT is automatically set to MYSQL and SET SQL is set ON.


Example

set sqldialect to vfp
 
set sql to mysql
set sql on
