Hi AIGLES
Thanks for your response.
I had made a little change in input too.I am posting here both input and output.



Code:
ALTER TABLE tbla
ADD  ( cola1  VARCHAR2(11),
       cola2  VARCHAR2(12)  );

ALTER TABLE tbla  ADD CONSTRAINT PK_tbla PRIMARY KEY (cola1);

ALTER TABLE tblb
ADD  ( colb1  VARCHAR2(21),
       colb2  VARCHAR2(22)  );

ALTER TABLE tblb ADD CONSTRAINT PK_tblb PRIMARY KEY (colb1,colb2);
ALTER TABLE tblc ADD CONSTRAINT PK_tblc PRIMARY KEY (colc0);

ALTER TABLE tblc
ADD  ( colc1  VARCHAR2(31),
       colc2  VARCHAR2(32),
       colc3  VARCHAR2(32)  );

ALTER TABLE tbld ADD CONSTRAINT PK_tbld PRIMARY KEY (cold0,cold2,cold3);
ALTER TABLE tblc ADD col1 CHAR(3) NULL;
ALTER TABLE tblb ADD col1 CHAR(3) NULL;
ALTER TABLE tbla ADD col1 CHAR(3) NULL;
ALTER TABLE tbld ADD col1 CHAR(3) NULL;
ALTER TABLE tbla ADD col1 CHAR(3) NULL;

Desired Output:

Code:
TABLES
TABLE_NAME	COLUMN_NAME	DATATYPE	

tbla		cola1		VARCHAR2(11)	NOT NULL
		cola2		VARCHAR2(12)	NOT NULL
tblc		colc1  		VARCHAR2(31)	NOT NULL
       		colc2  		VARCHAR2(32)	NOT NULL
       		colc3  		VARCHAR2(32)	NOT NULL
tblc		col1		CHAR(3) 	NULL
tbla		col1 		CHAR(3)		NULL
tbla 		col1		CHAR(3)		NULL

NO IMPACT
TABLE_NAME

tbla		CONSTRAINT 
tblb
tblb		CONSTRAINT
tblc		CONSTRAINT
tbld		CONSTRAINT

alter_trigger

ALTER 
TRIGGER(7)						   SQL Commands 						  ALTER TRIGGER(7)

NAME

       ALTER TRIGGER - change the definition of a trigger

SYNOPSIS

       ALTER TRIGGER name ON table RENAME TO newname

DESCRIPTION

       ALTER TRIGGER changes properties of an existing trigger. The RENAME clause changes the name of the given trigger without otherwise changing
       the trigger definition.

       You must own the table on which the trigger acts to be allowed to change its properties.

PARAMETERS

       name   The name of an existing trigger to alter.

       table  The name of the table on which this trigger acts.

       newname
	      The new name for the trigger.

NOTES

       The ability to temporarily enable or disable a trigger is provided by ALTER TABLE [alter_table(7)], not by  ALTER  TRIGGER,  because  ALTER
       TRIGGER has no convenient way to express the option of enabling or disabling all of a table's triggers at once.

EXAMPLES

       To rename an existing trigger:

       ALTER TRIGGER emp_stamp ON emp RENAME TO emp_track_chgs;

COMPATIBILITY

       ALTER TRIGGER is a PostgreSQL extension of the SQL standard.
