Gireesh Puthumana commented on SQOOP-2949:
------------------------------------------
Same issue can happen even when the min & max value has no single quotes but
the split range values that are generated has.
May be we should escape quotes from the range values in general - not just from
the min/max values.
> SQL Syntax error when split-by column is of character type and min or max
> value has single quote inside it

> Did a sqoop import from mysql table "emp", with split-by column "ename",
> which is a varchar(100) type.
> +Used below command:+
> sqoop import --connect jdbc:mysql://localhost/testdb --username root
> --password ***** --table emp --m 2 --target-dir /sqoopTest/5 --split-by ename;
> +Ename has following records:+
> | ename |
> | gireesh |
> | aavesh |
> | shiva' |
> | jamir |
> | balu |
> | santosh |
> | sameer |
> Min value is "aavesh" and max value is "shiva'" (please note the single quote
> inside max value).
> When run, it tried to execute below query in mapper 2 and failed:
> SELECT `ename`, `eid`, `deptid` FROM `emp` AS `emp` WHERE ( `ename` >=
> 'jd聯聭聪G耀' ) AND ( `ename` <= 'shiva'' )
