SQL Script Syntax

• Standard SQL syntax with statement delimiter ;
• BEGIN .. END; blocks used for triggers and anonymous do blocks

Compatibility

• SAP HANA DDL can be used unchanged in a Flyway migration.
• Any SAP HANA sql script executed by Flyway, can be executed by SAP HANA (after the placeholders have been replaced).

Example

/* Single line comment */
CREATE TABLE t (a INT, b NVARCHAR(10), c NVARCHAR(20));
CREATE INDEX idx ON t(b);

CREATE COLUMN TABLE A (A VARCHAR(10) PRIMARY KEY, B VARCHAR(10));
CREATE FULLTEXT INDEX i ON A(A) FUZZY SEARCH INDEX OFF SYNC;

/*
Multi-line
comment
*/

CREATE TABLE TARGET ( A INT);
CREATE TABLE control_tab(id INT PRIMARY KEY, name VARCHAR(30), payment INT);
CREATE TABLE message_box(message VARCHAR(200), log_time TIMESTAMP);

-- Triggers with complex BEGIN END; blocks
CREATE TRIGGER TEST_TRIGGER_FOR_INSERT
AFTER INSERT ON TARGET
BEGIN
 DECLARE v_id        INT := 0;
 DECLARE v_name      VARCHAR(20) := '';
 DECLARE v_pay       INT := 0;
 DECLARE v_msg       VARCHAR(200) := '';
 DELETE FROM message_box;
 FOR v_id IN 100 .. 103 DO
     SELECT name, payment INTO v_name, v_pay FROM control_tab WHERE id = :v_id;
     v_msg := :v_name || ' has ' || TO_CHAR(:v_pay);
     INSERT INTO message_box VALUES (:v_msg, CURRENT_TIMESTAMP);
 END FOR;
END;

CREATE TABLE SAMPLE ( A INT);
CREATE TRIGGER TEST_TRIGGER_WHILE_UPDATE
AFTER UPDATE ON TARGET
BEGIN
 DECLARE found INT := 1;
 DECLARE val INT := 1;
 WHILE :found <> 0 DO
     SELECT count(*) INTO found FROM sample WHERE a = :val;
     IF :found = 0 THEN
         INSERT INTO sample VALUES(:val);
     END IF;
     val := :val + 1;
 END WHILE;
END;

-- Anonymous blocks
DO
BEGIN
    DECLARE v_count INT;
    CREATE TABLE TAB1 (I INTEGER); 
    FOR v_count IN 1..10 DO
        INSERT INTO TAB1 VALUES (:v_count);
    END FOR;
END;

-- Placeholders
INSERT INTO ${tableName} (name) VALUES ('Mr. T');
