Devart Forums

I have installed and configured dotConnect postgresql professional trial just fine, just installed with your release from christmas.

This is the - theoretically - simple statement I am having trouble with I considered using CONCAT() instead of ||, but we are still using postgresql 8.4, so there is no such function avaible.

When I try to save a statement like that Visual Studio 2013 gives me the following error: After that I can continue, but it doesn't update the columns at all, so the columns in the designer don't match to these of the actual statement at all. Basicly I could only run a typeless DataTable...

I assumed the parser has no idea about postgresql syntax at all. Does that mean I can't use strong typed DataTables with custom fields at all? Plain DataTables automatically derived from tables just work fine and the fact that the tableadapters generated that way require a Devart.Data.PostgreSql.PgSqlConnection instead of a normal SqlConnection object also tells me I can't be missing to use your driver at all.

Is this a known restriction? I am doing there something wrong? I mean, I can't find anything in the forum, I can't be the first person to try to concat string using ||... obviously I am doing something wrong. But what? Please give me any leads.

Please use our DataSet wizard: the Tools > PostgreSQL > DataSet Wizard menu of Visual Studio. It is adjusted for working with PostgreSQL databases and parses PostgreSQL-specific SQL queries successfully.

Thank you very much. That indeed was the important thing I was missing. Using the Wizzard from the menu solves that issue and always me to use postgresql syntax in the statement creator.
