CREATE UNIQUE INDEX "TEST_SCHEMA"."TEST_INDEX"
ON TEST_SCHEMA.TEST_TABLE ( A, B DESC, C DESC )

Rename Index

MaxDB allows to rename an existing index. After selecting the index and entering the new index name, DtSQL can generate and execute the SQL to rename the index.

Sample : RENAME INDEX "TEST_INDEX" ON "TEST_SCHEMA"."TEST_TABLE" TO TESTINDEX

Drop Index

MaxDB allows to drop an existing index. After selecting the index name, DtSQL can generate and execute the SQL to delete the index.

Sample : DROP INDEX "TEST_INDEX" ON "TEST_SCHEMA"."TEST_TABLE"

Trigger

Create Trigger

MaxDB allows to create a new trigger. After entering the trigger name and trigger actions, DtSQL can generate and execute the SQL to create the trigger.

Sample :
CREATE TRIGGER "TEST_TRIGGER"
FOR "TEST_SCHEMA"."TEST_TABLE"
AFTER INSERT
EXECUTE (
UPDATE "TEST_SCHEMA"."TEST_TB" SET COL1 = COL1 + 1;
)

Drop Trigger

MaxDB allows to drop an existing trigger. After selecting the trigger name, DtSQL can generate and execute the SQL to delete the trigger.

Sample : DROP TRIGGER "TEST_TRIGGER" OF "TEST_SCHEMA"."TEST_TABLE"

Constraint

Create Primary Key

MaxDB allows to create a primary key for a table. After selecting the table columns, DtSQL can generate and execute the SQL to create the primary key.

Sample :
