This message is shown when SnowConvert finds a DEFAULT SESSION and the data type is NOT a VARCHAR. If that is the case, the data type is changed to VARCHAR and a message is added.
CREATE TABLE TableExample(ColumnExample INTEGER DEFAULT SESSION,ColumnExample2 VARCHAR DEFAULT SESSION)
CREATE TABLE PUBLIC.TableExample(ColumnExample VARCHAR DEFAULT CURRENT_SESSION() /*** MSC-WARNING - MSCEWI2019 - CONVERTED FROM INTEGER TO VARCHAR FOR CURRENT_SESSION DEFAULT ***/,ColumnExample2 VARCHAR DEFAULT CURRENT_SESSION());
Let's take a look at the example. Note that ColumnExample has a data type INTEGER with DEFAULT SESSION. Since the data type is not VARCHAR, in the output it is transformed to VARCHAR.
The data type of ColumnExample2 doesn't change since it is already VARCHAR.
