Schema

Create Schema

Mckoi allows to create a new schema. After entering the schema name, DtSQL can generate and execute the SQL to create the new schema.

Sample : CREATE SCHEMA "TEST_SCHEMA"

Drop Schema

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

Sample : DROP SCHEMA "TEST_SCHEMA" RESTRICT

Table

Create Table

Mckoi 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 DEFAULT 1 NOT NULL ,
b char ( 12 ) DEFAULT 'abc' NOT NULL,
c decimal ( 12, 2 ) ,

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

Truncate Table

Mckoi allows to truncate an table. After entering the table name, DtSQL can delete all data in the table.

Sample : DELETE FROM "TEST_SCHEMA"."TEST_TABLE"

Drop Table

Mckoi 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

Mckoi 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'

Drop Column

Mckoi 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

View

Create View

Mckoi 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

Mckoi 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"

Constraint

Create Primary Key

Mckoi 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

Mckoi 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

Mckoi 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

Mckoi 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

Mckoi 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 _ANONYMOUS_CONSTRAINT_7

Drop Foreign Key

Mckoi 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 "_ANONYMOUS_CONSTRAINT_7"

Drop Check Constraint

Mckoi 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

Mckoi 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"

Sequence

Create Sequence

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

Sample :
CREATE SEQUENCE "TEST_SCHEMA"."TEST_SEQ"
INCREMENT 2
MINVALUE 1
MAXVALUE 10000
START 10
CACHE 20
CYCLE

Drop Sequence

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

Sample : DROP SEQUENCE "TEST_SCHEMA"."TEST_SEQ"
