load multiple table in the same database from sql to qlikview - sql

Question

I am trying to load all the tables in "ABCD_BKP" which starts with TEST_
The tables in my database are as follows:
ABCD_BKP
TEST_1
TEST_2
TEST_3
And I am trying to load it as per below but it does not seem to work.
SELECT *
FROM "ABCD_BKP".dbo.TEST_*

Answer 1

To load all tables you need to have list with the tables first and loop through this list and load the tables one by one.
For example if you are using MSSQL your script will be:
// Get all tables in "ABCD_BKP"
TableNames:
SQL
SELECT
TABLE_NAME
FROM
"ABCD_BKP".dbo.Tables
;
// Filter only table names that are starting with "TEST_"
Test_TableNames:
LOAD DISTINCT
TABLE_NAME
RESIDENT
TableNames as TestTables
WHERE
LEFT(TABLE_NAME, 5) = 'TEST_'
;
DROP TABLE TableNames; // the table with all table names is no longer needed
FOR i = 1 TO FieldValue('TestTables') // loop through all "TEST_*" tables
LET vTableName = FieldValue( 'TestTables', $(i) ); // current iteration table name
$(vTableName): //give our QV table the same name as the SQL table
SQL
SELECT
*
FROM
"ABCD_BKP".dbo.$(vTableName) // load the sql table in QV
;
NEXT
DROP TABLE Test_TableNames; // drop the QV table that contains the list with the "TEST_" tables
The sql to get the list with the tables in database is different for each database
