> Project: Tajo
> Issue Type: Bug
> Reporter: Keuntae Park
> Assignee: Jihun Kang
> Priority: Minor
>
> With MySQL as catalog storage, I experienced following create table statement
> did not work.
> {code}
> create table test ("name" text, "Name" text);
> {code}
> Error log is as followings:
> {code}
> 2015-01-14 15:25:27,386 ERROR org.apache.tajo.catalog.CatalogServer:
> java.sql.BatchUpdateException: Duplicate entry '1221-Name' for key 'PRIMARY'
> org.apache.tajo.catalog.exception.CatalogException:
> java.sql.BatchUpdateException: Duplicate entry '1221-Name' for key 'PRIMARY'

> org.apache.tajo.catalog.AbstractCatalogClient$16.call(AbstractCatalogClient.java:351)
> {code}
> With Google's assistance, I found that
> MySQL primary key column does not distinguish the case of characters.
> I made above statement work with following COLUMS schema (according to
> Google's advice):
> {code}
> CREATE TABLE COLUMNS (
> TID INT NOT NULL,
> COLUMN_NAME VARCHAR(255) BINARY NOT NULL,
> ORDINAL_POSITION INT NOT NULL,
> DATA_TYPE CHAR(16),
> TYPE_LENGTH INTEGER,
> PRIMARY KEY (TID, COLUMN_NAME),
> FOREIGN KEY (TID) REFERENCES TABLES (TID) ON DELETE CASCADE
> )
> {code}
> I'm not sure this is proper approach to solve the problem
> because I'm not familiar with Catalog :)
> Please, check the situation.
