Bit-Field processed incorrectly

[codeage]

Reproduction steps:

1. Add a bit field named 'SEX' to the source table and set the default value to 0;
2. Run schemasync to create the patch script;
3. Import the patch script into mysql;

Following script fails:

ALTER TABLE `table1` ADD COLUMN `SEX` bit(1) NULL DEFAULT 'b'0'' AFTER `LEVEL`;

with error:

ERROR 1064 (42000) at line 9: You have an error in your SQL syntax; 
check the manual that corresponds to your MySQL server version for the right 
syntax to use near '0'' AFTER `LEVEL`' at line 1

This error is caused by the extra single quotation surrounding b'0'. Correct script should be:

ALTER TABLE `table1` ADD COLUMN `SEX` bit(1) NULL DEFAULT b'0' AFTER `LEVEL`;
