I will strongly recommend removing the quotes around table name and column
names. Else you may have challenges porting application to PG. As PG by
default refers to object names in small case unless you out quotes around
them.

So after migration a statement like

Select * from DLR_FAM_MRKTSHR_FY_END;

would fail.

Also about the error, see what is before this create table statement. Make
sure there is a semi colon to terminate the statement before the CREATE
table.

How are you running it? psql?

Re: [GENERAL] Migrating data from DB2 zOS to PostgreSQL

[Swapnil Vaze]

Hello Julien,

We created DDLs from DB2 zOS system and tried to run script in below format:

 ./db2topg.pl -f sql1.txt -o testdir

It throws below error:

I don't understand  at ./db2topg.pl line 880,  line 24.

For testing we used file with below content:

cat sql1.txt
-- This CLP file was created using DB2LOOK Version "10.5"
-- Timestamp: Tue Dec  6 04:14:28 CST 2016
-- Database Name: DB239
-- Database Manager Version: DB2 Version 11.1.0
-- Database Codepage: 1208



-- DDL Statements for Table "A90DVDT"."DLR_FAM_MRKTSHR_FY_END"


CREATE TABLE "A90DVDT"."DLR_FAM_MRKTSHR_FY_END"
(
 "DEALER_ID"  CHAR(6)  NOT NULL ,
 "MKTSHR_MONTH"  DATE NOT NULL ,
 "L12_DP_DLR_IN_AOR"  DECIMAL(15,6) ,
 "L12_DP_DLR_OUT_AOR"  DECIMAL(15,6) ,
 "L12_DP_DLR_SHARE"  DECIMAL(8,5) ,
 "L12_SA_DLR_SHARE"  DECIMAL(8,5) ,
 "L12_CA_DLR_SHARE"  DECIMAL(8,5) ,
 "L12_U90_DLR_IN_AOR"  DECIMAL(15,6) ,
 "L12_U90_DLR_OUT_AOR"  DECIMAL(15,6) ,
 "L12_U90_DLR_SHARE"  DECIMAL(8,5)
);

Thanks,
Swapnil

You can use this utility: https://github.com/dalibo/db2topg

The README should provide all needed informations.
