[8.0] TransformationDB: removing BLOB in favor of TEXT for non-binary data

[fstagni]

This of course requires a manual intervention, that can be done at any time (not really depending from this release). On LHCb clone of TransformationDB it took rather long:

MySQL [TransformationDB]> ALTER TABLE `TransformationMetaQueries` MODIFY COLUMN `MetaDataValue` TEXT;
Query OK, 0 rows affected (0.11 sec)
Records: 0  Duplicates: 0  Warnings: 0

MySQL [TransformationDB]> ALTER TABLE `AdditionalParameters` MODIFY COLUMN `ParameterValue` LONGTEXT;
Query OK, 2353784 rows affected (3 min 39.64 sec)
Records: 2353784  Duplicates: 0  Warnings: 0

MySQL [TransformationDB]> ALTER TABLE `Transformations` MODIFY COLUMN `Body` LONGTEXT;
Query OK, 145680 rows affected (27 min 9.51 sec)
Records: 145680  Duplicates: 0  Warnings: 0

MySQL [TransformationDB]> 
MySQL [TransformationDB]> ALTER TABLE `Transformations` MODIFY COLUMN `LongDescription` TEXT;

Query OK, 145680 rows affected (23 min 21.02 sec)
Records: 145680  Duplicates: 0  Warnings: 0

(I will add the above to the wiki).

It can anyway be tested in the meanwhile in the coming DIRAC hackathon.

You can modify more than one column per ALTER TABLE
