MySQL Data Source Parameter Issue

edited March 2018 in FastReport .NET
I have added a bit more info...

I am setting up a datasource and have entered a query.

When the where clause is

where

<fieldname> = '{D15B35A9-3A38-4E41-B2C6-6C6DF23A2061}'
and <fieldname2> = '{7DED468D-6506-4CA3-B711-1105C4532A23}'
and <fieldname3> = '{FECD00C7-8C16-4D49-AC6A-DE5D5698219A}'

selecting view data in the data pane works fine and gives me the expected results.

but when its set up as

where
<fieldname> = @p1
and <fieldname2> = @p2
and <fieldname3> = @p3

and parameters are set up as

then selecting view data returns nothing.

Not sure what the problem is but suspect it may be the expression is not set but I don't know what the expression should be.

Database is mysql

So I read the manual a bit more and further defined the parameters in the query and added 3 parameters in the data bain . Which you can see in the screen shot and added them in the Query Wizard Parameters screen/

Still no happiness in getting the query to populated the defaults so something is still missing

This is the property of the first parameter.

What am I missing to get the default to load into the query when I preview the report ? I suspect it is the expression in the parameter definition...

Again any help is appreciated.

    the data type is varchar(38) for all parameter fields.

    Works fine for you. Not for me. That's a problem. I noticed that your select is fieldname = @p1 and then in the parameter definition you define it as @p1 not simply as p1. That's not what the manual seems to say...


    Anyway this is definitely a problem for me. Is there anyway to debug this ?

    fully functional demo of fastreport with mysql db, https://mega.nz/#!w00lXSCL!H8uuUmMJ...Frz5jRbQ8JWrKBc

    Notes:
    1. attach database sakila to mysql server
    2. register FastReport.MySQL.dll to fastreport designer plugin (dependency: MySql.Data.dll)
    3. MySql.Data.dll is mysql-connector-net-6.10.6
    4. resolve sakila db connection in untitled.frx and copy it to folder 'compiledprogram' (i didnt use odbc [img]style_emoticons/<#EMO_DIR#>/biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" /> ) 5. run WindowsFormsApplication1.exe[/img]

    I finally got back. I built the fastreport.mysql.dll plug in as instructed by help desk. It still did not work. I looked at your example and tweaked a few things and then it started to work. Thanks for your help. I will now try to get this working in my web server and see what happens.

    Thank you for your help.
