buildCheckQuery()

buildCheckQuery ( )

protected

Checks a DDL query to see if it is a known type If yes, build a check query to see if the DDL has been run on the database. If successful, the $msgElements, $queryType, $checkStatus and $checkQuery fields are populated. The $msgElements contains the text to create the user message. The $checkQuery contains the SQL query to check whether the schema change has been run against the current database. The $queryType contains the type of DDL query that was run (for example, CREATE_TABLE, ADD_COLUMN, CHANGE_COLUMN_TYPE, ADD_INDEX). The $checkStatus field is set to zero if the query is created

If not successful, $checkQuery is empty and , and $checkStatus is -1. For example, this will happen if the current line is a non-DDL statement.

When we made the UTF8MB4 conversion then text becomes medium text - so loosen the checks to these two types otherwise (for example) the profile fields profile_value check fails - see https://github.com/joomla/joomla-cms/issues/9258

fixInteger()

fixInteger (   $type1,   $type2  )

private

Fix up integer. Fixes problem with MySQL integer descriptions. On MySQL 8 display length is not shown anymore. This means we have to match e.g. both "int(10) unsigned" and "int unsigned", or both "int(11)" and "int" and so on. The same applies to the other integer data types "tinyint", "smallint", "mediumint" and "bigint".
