Cursor Declaration
Before using a cursor in an application, the cursor must be declared. The syntax for declaring a cursor is:
EXEC SQL DECLARE cursor_name CURSOR FOR
     select_statement;
The DECLARE CURSOR statement assigns a name to the cursor and associates the cursor with a SELECT statement to be used to retrieve data. A cursor is always associated with a SELECT statement. The select is executed when the cursor is opened. The cursor_name can be specified using a string literal or a host language string variable. The cursor name cannot exceed 32 bytes and can be assigned dynamically. For details, see Summary of Cursor Positioning.
