Question

I create the following two tables that only differs the case:

tables.sql:

CREATE TABLE T1 (C1 INTEGER);
INSERT INTO T1 VALUES (1);
CREATE TABLE "t1" (C1 INTEGER);
INSERT INTO "t1" VALUES (2);
CREATE TABLE T2 (C1 INTEGER, "c1" integer);
INSERT INTO T2 VALUES (3, 4);

Command

db2 -tvf tables.sql

When I want to query the tables, directly from the CLP, I cannot differentiate the two types of case. How can I do a query to table T1 and another to table t1. The same for both columns C1 and c1?

Answer 1

In order to query those tables from CLP in Windows, you have to do:

For table T1 (The simplest one):

db2 select * from T1

or (This is the way in Linux because of the *)

db2 "select * from T1"

For table t1

db2 "select * from ""t1"""

For the columns is similar

db2 select C1 from T2

For the other

db2 "select ""c1"" from T2"

Make sure that the whole command is involve in quotes. If you issue this command:

db2 select ""c1"" from T2

It will return C1 instead. The same for this command:

db2 select * from ""t1""

with T1 being returned.
