The SELECT statement may contain parameter markers like those used in other dynamic SQL statements 3 The program uses the PREPARE statement to pass the statement string to the DBMS, which parses, validates, and optimizes the statement and generates an application plan This is identical to the PREPARE processing used for other dynamic SQL statements 4 The program uses the DESCRIBE statement to request a description of the query results that will be produced by the query The DBMS returns a column-by-column description of the query results in a SQL Data Area (SQLDA) supplied by the program, telling the program how many columns of query results there are, and the name, data type, and length of each column The DESCRIBE statement is used exclusively for dynamic queries 5 The program uses the column descriptions in the SQLDA to allocate a block of memory to receive each column of query results.

18:

The program may also allocate space for an indicator variable for the column The program places the address of the data area and the address of the indicator variable into the SQLDA to tell the DBMS where to return the query results..

Dynamic SQL *

Part V:

Triggers can also be used to provide extended forms of referential integrity. For example, DB2 initially provided cascaded deletes through its CASCADE delete rule but did not support "cascaded updates" if a primary key value is changed. This limitation need not apply to triggers, however. The following SQL Server trigger cascades any update of the OFFICE column in the OFFICES table down into the REP_OFFICE column of the SALESREPS table: CREATE ON FOR AS TRIGGER CHANGE_REP_OFFICE OFFICES UPDATE IF UPDATE (OFFICE) BEGIN UPDATE SALESREPS SET SALESREPS.REP_OFFICE = INSERTED.OFFICE FROM SALESREPS, INSERTED, DELETED WHERE SALESREPS.REP_OFFICE = DELETED.OFFICE END

without any input parameters, conforms to the SQL2 standard. If the dynamic query specified parameters, they could be passed to the DBMS either as a series of host variables or via a SQL2 descriptor. The SQL2 OPEN statement using host variables is identical to the DB2 style, shown in the program in Figure 18-13. The SQL2 OPEN statement using a descriptor is parallel to the SQL2 EXECUTE statement using a descriptor, and differs from the DB2 style. For example, the OPEN statement of Figure 18-14:

6 A dynamic version of the OPEN statement asks the DBMS to start executing the query and passes values for the parameters specified in the dynamic SELECT statement The OPEN statement positions the cursor before the first row of query results 7 A dynamic version of the FETCH statement advances the cursor to the first row of query results and retrieves the data into the program s data areas and indicator variables Unlike the static FETCH statement, which specifies a list of host variables to receive the data, the dynamic FETCH statement uses the SQLDA to tell the DBMS where to return the data Subsequent executions of this dynamic FETCH statement move through the query results row by row, advancing the cursor to the next row of query results and retrieving its data into the program s data areas 8.

OPEN qrycursor USING DESCRIPTOR :parmda;

The CLOSE statement ends access to the query results and breaks the association between the cursor and the query results This CLOSE statement is identical to the static SQL CLOSE statement; no extensions are required for dynamic queries The programming required to perform a dynamic query is more extensive than the programming for any other embedded SQL statement However, the programming is typically more tedious than complex Figure 18-9 shows a small query program that uses dynamic SQL to retrieve and display selected columns from a user-specified table The callout numbers in the figure identify the eight steps in the preceding list The program in the figure begins by prompting the user for the table name and then queries the system catalog to discover the names of the columns in that table.

is changed for SQL2 into this OPEN statement:

It asks the user to select the column(s) to be retrieved and constructs a dynamic SELECT statement based on the user s responses The step-by-step mechanical construction of a select list in this example is very typical of database front-end programs that generate dynamic SQL In real applications, the generated select list might include expressions or aggregate functions, and there might be additional program logic to generate GROUP BY, HAVING, and ORDER BY clauses A graphical user interface would also be used instead of the primitive user prompting in the sample program However, the programming steps and concepts remain the same Notice that the generated SELECT statement is identical to the interactive SELECT statement that you would use to perform the requested query.
