Prepare command


PREPARE Identifier AS String


Creates a java.sql.PreparedStatement using the value of the String, accessible in ij by the Identifier given to it. If a prepared statement with that name already exists in ij, an error will be returned and the previous prepared statement will remain. Use the Remove command to remove the previous statement first. If there are any errors in preparing the statement, no prepared statement is created.

Any SQL statements allowed in the underlying connection's prepared statement can be prepared with this command.

If the Identifier specifies a connectionName, the statement is prepared on the specified connection.

ij> execute seeMenu;
