The DECLARE cursor-name statement identifies the cursor, the columns
selected, and the search criteria.
a) The column-names in the SELECT clause (TBE_NME, TBE_DTE, FLAG)
are those of the table.
b) Note that if the WHERE clause is missing we are reading the whole table.
c). We set the Cobol data-name FLAG = 'H' or FLAG ='E' to the correct value since it is used as the search criteria.
that u have declared as below
EXEC SQL DECLARE CNTL_TABLE_CSR2 CURSOR WITH HOLD FOR
WHERE FLAG = 'H' or FLAG ='E'
FOR UPDATE OF FLAG
For fetching the record means, only one record dont keep FETCH SQL statement in loop such as until SQLCODE = 100 or some other means
do it in a one shot and move it to cobol variables and display it in terminal
SET FLAG= . . . . .
WHERE CURRENT OF CURSOR-names
IF SQLCODE TO EQUAL TO ZERO
the very first record that satisfies the condition will be displayed.
