OK, I realised it was a PostgreSQL error. The solution is to force PostgreSQL to interpret the parameter as a timestamp SELECT *FROM logWHERE CASE WHEN $P{timestampFrom}::timestamp IS NULL THEN TIMESTAMP >= '-infinity' ELSE TIMESTAMP >= $P{timestampFrom} END[/code]

I'm really struggling to get my query to work against my PostgreSQL database. Essentially, my query can be delimited by a timestamp, a parameter that the user can input, but which can also be empty. If no timestamp is provided, I must tell PostgreSQL to use '-infinity' instead. I tried writing the conditional statement below, but I get the error 'Could not determine data type of parameter $1' Can anyone tell me what's wrong with my query? SELECT *FROM logWHERE CASE WHEN $P{timestampFrom} IS NULL THEN timestamp >= '-infinity' ELSE timestamp >= $P{timestampFrom} END[/code]$P{timestampFrom} is a sql.Timestamp parameter.
