    SymmetricDS space in column name MSSQL source fix 6 μέρες left
    ΕΠΙΒΕΒΑΙΩΜΕΝΟ

    Hello, We have setup a replication from MSSQL to MySQL. SymmetricDS auto creates the schema, but one table in source (MSSQL) contains trailing space => 'Artikelnr '. This gives an error with MySQL. This project is about fixing this issue so it automatically corrects it and creates the table. <!DOCTYPE database SYSTEM ""> <database name="dataextractor"> <table name=""> <column name="Artikelnr " type="VARCHAR" size="50"> <platform-column name="mssql2016" type="varchar" size="50"/> </column> Must be future proof so no one time manual fixes. A pastebin log file can be supplied for more info.
