Table

Create Table

Ingres allows to create a new table. After entering the table name and column information, DtSQL can generate and execute the SQL to create the table.

  • Column Name
  • Column Type
  • Length/Precesion
  • Scale (decimal)
  • Default Value
  • Nullable
  • Primary Key
  • Unique

Sample :
CREATE TABLE "TEST_SCHEMA"."TEST_TABLE" (
a bigint NOT NULL DEFAULT 1,
b char ( 12 ) NOT NULL DEFAULT 'abc',
c decimal ( 12, 2 ) NOT NULL DEFAULT 12.12 ,

PRIMARY KEY ( a, b ),
UNIQUE ( b,c )
)

Truncate Table

Ingres does not allows to truncate an table and deleting table is used instead. After entering the table name, DtSQL can delete all data in the table.

Sample : DELETE FROM "TEST_SCHEMA"."TEST_TABLE"

Drop Table

Ingres allows to drop an existing table. After entering the table name, DtSQL can generate and execute the SQL to drop the table.

Sample : DROP TABLE "TEST_SCHEMA"."TEST_TABLE"

Column

Add Column

Ingres allows to add a new column to an existing table. After selecting the table and entering column information, DtSQL can generate and execute the SQL to add the new column to the table.

  • Column Name
  • Column Type
  • Length/Precesion
  • Scale (decimal)
  • Default Value
  • Nullable

Sample :
ALTER TABLE
"TEST_SCHEMA"."TEST_TABLE"
ADD
d varchar(20) NOT NULL DEFAULT 'def'

Change Data Type

Ingres allows to change the column data. After selecting the new data type, DtSQL can generate and execute the SQL to change the column data type.

Sample :
ALTER TABLE "TEST_SCHEMA"."TEST_TABLE"
ALTER COLUMN F BIGINT

Drop Column

Ingres allows to delete an existing column. After selecting the column, DtSQL can generate and execute the SQL to delete the column.

Sample :
ALTER TABLE "TEST_SCHEMA"."TEST_TABLE"
DROP COLUMN F RESTRICT

View

Create View

Ingres allows to create a new view. After entering the view name and select SQL, DtSQL can generate and execute the SQL to create the view.

Sample :
CREATE VIEW "TEST_SCHEMA"."TEST_VIEW"
AS
SELECT * FROM "TEST_SCHEMA"."TEST_TABLE"

Drop View

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

Sample : DROP VIEW "TEST_SCHEMA"."TEST_VIEW"

Index

Create Index

Ingres allows to create a new index. After selecting the table columns and entering the view name, DtSQL can generate and execute the SQL to create the index.

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

Drop Index

Ingres 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_SCHEMA"."TEST_INDEX"

Trigger

Create Trigger

Ingres 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_SCHEMA"."TEST_TRIGGER"
AFTER INSERT
ON "TEST_SCHEMA"."TEST_TABLE"
FOR EACH ROW
EXECUTE PROCEDURE "TEST_SCHEMA"."TEST_PROC"

Drop Trigger

Ingres 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_SCHEMA"."TEST_TRIGGER"

Constraint

Create Primary Key

Ingres 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 :
ALTER TABLE
"TEST_SCHEMA"."TEST_TABLE"
ADD
PRIMARY KEY ( B, C )

Create Foreign Key

Ingres allows to create a foreign key for a table to reference to another table. After selecting the table columns and referenced table columns, DtSQL can generate and execute the SQL to create the foreign key.

Sample :
ALTER TABLE
"TEST_SCHEMA"."TEST_TABLE"
ADD
FOREIGN KEY ( A, C )
REFERENCES "TEST_SCHEMA"."TEST_TB" (B, A )

Create Check Constraint

Ingres allows to create a check constraint for a table column. After entering the check constraint name and check action, DtSQL can generate and execute the SQL to create the check constraint.

Sample :
ALTER TABLE
"TEST_SCHEMA"."TEST_TABLE"
ADD CONSTRAINT "TEST_CHECK"
CHECK ( C > 10 )

Create Unique Constraint

Ingres allows to create an unique constraint for a table columns. After entering the unique constraint name and selecting table columns, DtSQL can generate and execute the SQL to create the unique constraint.

Sample :
ALTER TABLE
"TEST_SCHEMA"."TEST_TABLE"
ADD CONSTRAINT "TEST_UNIQUE"
UNIQUE ( B, C )

Drop Primary Key

Ingres allows to drop an existing primary key. After selecting the primary key, DtSQL can generate and execute the SQL to delete the primary key.

Sample :
ALTER TABLE "TEST_SCHEMA"."TEST_TABLE"
DROP CONSTRAINT "$test2_u0000018a00000000" RESTRICT

Drop Foreign Key

Ingres allows to drop an existing foreign key. After selecting the foreign key, DtSQL can generate and execute the SQL to delete the foreign key.

Sample :
ALTER TABLE "TEST_SCHEMA"."TEST_TABLE"
DROP CONSTRAINT "$test2_u0000018b00000000" RESTRICT

Drop Check Constraint

Ingres allows to drop an existing check constraint. After selecting the check constraint, DtSQL can generate and execute the SQL to delete the check constraint.

Sample :
ALTER TABLE
"TEST_SCHEMA"."TEST_TABLE"
DROP CONSTRAINT "TEST_CHECK"

Drop Unique Constraint

Ingres allows to drop an existing unique constraint. After selecting the unique constraint, DtSQL can generate and execute the SQL to delete the unique constraint.

Sample :
ALTER TABLE
"TEST_SCHEMA"."TEST_TABLE"
DROP CONSTRAINT "TEST_UNIQUE"

TOP
 

Procedure

Create Procedure

Ingres allows to create procedures. After entering the procedure name, parameter names and procedure body, DtSQL can generate and execute the SQL to create the procedure.

Sample :
CREATE PROCEDURE "TEST_SCHEMA"."TEST_PROC"
( PARAM1 VARCHAR(20), PARAM2 BIGINT, PARAM3 TIMESTAMP)
AS
BEGIN
UPDATE TESTDB.TESTTB SET COL1 = COL1 + 1;
END

Drop Procedure

Ingres allows to drop an existing procedure. After selecting the procedure, DtSQL can generate and execute the SQL to delete the procedure.

Sample : DROP PROCEDURE "TEST_SCHEMA"."TEST_PROC"

TOP
 

Sequence

Create Sequence

Ingres allows to create sequences. After entering the sequence parameters, DtSQL can generate and execute the SQL to create the sequence.

Sample :

INCREMENT BY 2
MINVALUE 1
MAXVALUE 10000
START WITH 10
CACHE 20
CYCLE
ORDER

Drop Sequence
