Sql Syntax with comparison of Date

Hi, I'm having trouble with a Report done in iReport 4.6. I have a very simple SQL that doesn't work.

The SQL is

SELECT p.apynom as apynom_prestador, a.fechatur, a.nroficha, a.apynom, a.observacion, a.osoc, a.numero

FROM "admi0001" a

inner join arcpro p on p.prestador = a.prestador

WHERE a.fechatur = $P!{fechaturno}

order by a.fechatur

And I get the next error

Error filling print... Error executing SQL statement for : turnosdia

net.sf.jasperreports.engine.JRException: Error executing SQL statement for : turnosdia      at net.sf.jasperreports.engine.query.JRJdbcQueryExecuter.createDatasource(JRJdbcQueryExecuter.java:246)      at net.sf.jasperreports.engine.fill.JRFillDataset.createQueryDatasource(JRFillDataset.java:1073)      at net.sf.jasperreports.engine.fill.JRFillDataset.initDatasource(JRFillDataset.java:667)      at net.sf.jasperreports.engine.fill.JRBaseFiller.setParameters(JRBaseFiller.java:1235)      at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:859)      at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:804)      at net.sf.jasperreports.engine.fill.JRFiller.fill(JRFiller.java:61)      at net.sf.jasperreports.engine.JasperFillManager.fill(JasperFillManager.java:446)      at net.sf.jasperreports.engine.JasperFillManager.fill(JasperFillManager.java:276)      at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:745)      at com.jaspersoft.ireport.designer.compiler.IReportCompiler.run(IReportCompiler.java:891)      at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:572)      at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:997)

Print not filled. Try to use an EmptyDataSource...

I'm guessing it must be a format error with the dates. I have Postgres database and the field in the DB is defined as imestamp with time zone and the parameter in the Report as Date.

The weird thing about this is that if the comparison if > the SQL works well, but when i compare with "=" I get the syntax error.

Any clues of what am i doing wrong??

Thanks in advanced,

Andres
