The dynamic OPEN statement, shown in Figure 18-12, is a variation of the static OPEN statement. It causes the DBMS to begin executing a query and positions the associated cursor just before the first row of query results. When the OPEN statement completes successfully, the cursor is in an open state and is ready to be used in a FETCH statement. The role of the OPEN statement for dynamic queries parallels the role of the EXECUTE statement for other dynamic SQL statements. Both the EXECUTE and the OPEN statements cause the DBMS to execute a statement previously compiled by the PREPARE statement. If the dynamic query text includes one or more parameter markers, then the OPEN statement, like the EXECUTE statement, must supply values for these parameters. The USING clause is used to specify parameter values, and it has an identical format in both the EXECUTE and OPEN statements. If the number of parameters that will appear in a dynamic query is known in advance, the program can pass the parameter values to the DBMS through a list of host variables in the USING clause of the OPEN statement. As in the EXECUTE statement, the number of host variables must match the number of parameters, the data type of each host variable must be compatible with the type required by the corresponding parameter, and an indicator variable can be specified for each host variable, if necessary. Figure 18-13 shows a program excerpt where the dynamic query has three parameters whose values are specified by host variables. If the number of parameters is not known until runtime, the program must pass the parameter values using a SQLDA structure.

The FOR UPDATE clause provides this advance notice and can be considered a de facto standard of the embedded SQL Because of its widespread use, subsequent versions of the SQL standard include the IBM-style FOR UPDATE clause as an option in its DECLARE CURSOR statement However, unlike the IBM products, the SQL standard automatically assumes that a cursor is opened for update unless it is a scroll cursor or it is explicitly declared FOR READ ONLY The FOR READ ONLY specification in the DECLARE CURSOR statement appears in exactly the same position as the FOR UPDATE clause and explicitly tells the DBMS that the program will not.

C# .NET Code 39 Barcode Generator can create & print Code 39 barcode images in .NET 2.0 and above framework projects using C# class codes. attempt a positioned DELETE or UPDATE operation using the cursor. Because updateable cursors can significantly affect database overhead and performance, it is very important to understand the specific assumptions that your particular DBMS brand makes about the updateability of cursors, and the clauses or statements that can be used to override them. In addition, programs that explicitly declare whether their intention is to allow updates via an opened cursor are more maintainable. But you can t use a join in a DELETE statement. The parallel DELETE statement is illegal: Figure 18-13. DELETE FROM ORDERS, SALESREPS WHERE REP = EMPL_NUM AND NAME = 'Sue Smith'; Error: More than one table specified in FROM clause was described for the EXECUTE statement earlier in the section EXECUTE with SQLDA. The same technique is used for the OPEN statement. Figure 18-14 shows a program excerpt like the one in Figure 18-13, except that it uses a SQLDA to pass parameters. Note carefully that the SQLDA used in the OPEN statement has absolutely nothing to do with the SQLDA used in the DESCRIBE and FETCH statements: I The SQLDA in the OPEN statement is used to pass parameter values to the DBMS for dynamic query execution. The elements of its SQLVAR array correspond to the parameter markers in the dynamic statement text. I The SQLDA in the DESCRIBE and FETCH statements receives descriptions of the query results columns from the DBMS and tells the DBMS where to place the retrieved query results. The elements of its SQLVAR array correspond to the columns of query results produced by the dynamic query. - 226 - The way to handle the request is with one of the subquery search conditions. Here is a valid form of the DELETE statement that handles the request: Delete the orders taken by Sue Smith. 18: DELETE FROM ORDERS WHERE REP = (SELECT EMPL_NUM FROM SALESREPS WHERE NAME = 'Sue Smith'); 4 rows deleted.
