CREATE TABLE "dbo"."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 )
)

Rename Table

Sybase ASE allows to rename an existing table. After entering the table name, DtSQL can generate and execute the SQL to rename the table.

Sample : sp_rename 'test_table', 'testtable'

  • Default Value
  • Nullable

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

Sample :
ALTER TABLE
"dbo"."test_table"
ADD
PRIMARY KEY ( b, c )

Create Foreign Key

Sybase ASE 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
"dbo"."test_table"
ADD
FOREIGN KEY ( a, c )
REFERENCES "dbo"."test_tb" ( col2, col1 )

Create Check Constraint

Sybase ASE 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
"dbo"."test_table"
ADD CONSTRAINT "test_check"
CHECK ( c > 10 )
