PREPARE
PREPARE
Name
PREPARE -- prepare a statement for execution
Synopsis
PREPARE name FROM string
Description
PREPARE prepares a statement dynamically
specified as a string for execution. This is different from the
direct SQL statement PREPARE, which can also
be used in embedded programs. The EXECUTE
command is used to execute either kind of prepared statement.
Parameters
- prepared_name
An identifier for the prepared query.
- string
A literal C string or a host variable containing a preparable
statement, one of the SELECT, INSERT, UPDATE, or
DELETE.
Examples
char *stmt = "SELECT * FROM test1 WHERE a = ? AND b = ?";
EXEC SQL ALLOCATE DESCRIPTOR outdesc;
EXEC SQL PREPARE foo FROM :stmt;
EXEC SQL EXECUTE foo USING SQL DESCRIPTOR indesc INTO SQL DESCRIPTOR outdesc;
Compatibility
PREPARE is specified in the SQL standard.
