Dear Siva,
Here is a Do While loop syntax and example,
Do While Loop:
The do..loop control statement is a script iteration construct which executes one or several statements until a logical condition is met.
Syntax:
do[ ( while | until ) condition ] [statements]
[exit do [ ( when | unless ) condition ] [statements]
loop[ ( while | until ) condition ]
Where:
condition is a logical expression evaluating to true or false.
statements is any group of one or more QlikView script statements.
The while or until conditional clause must only appear once in any do..loop statement, i.e. either after do or after loop. Each condition is interpreted only the first time it is encountered but is evaluated for every time it encountered in the loop.
If an exit do clause is encountered inside the loop, the execution of the script will be transferred to the first statement after the loop clause denoting the end of the loop. An exit do clause can be made conditional by the optional use of a when or unless suffix.
Since the do..loop statement is a control statement and as such is ended with either a semicolon or end-of-line, each of its three possible clauses (do, exit do and loop) must not cross a line boundary.
Examples:
Set a=1;
Do while a<10
Load * from file$(a).csv;
Let a=a+1;
Loop
For detail understanding, please go through QlikView Reference Manual, Page No. 236.
Kind regards,
Ishfaque Ahmed
