Serial Date Conversion in PSQL

Serial Date Conversion in PSQL

Serial Date Conversion in PSQL

I work with an application that uses a date format of the number of days passed since 01/01/0001.

Would any one know of the correct function to use to convert into a date through PSQL.  I can do the conversion usind DateSerial after linked to MS SQL or MS Excel, but I was curious to see what the equivalent would be when creating a PSQL view from the Pervasive Control Center.

For Example, our application would store 732342.  If I export into excel, I can subtract 693594 from it to get a value of 38748.  This value represents the number of days since 01/01/1901.  When formatted as a date in Excel it would then show correctly as 01/31/2006.  

RE: Serial Date Conversion in PSQL

What version of PSQL are you using?  There isn't a DateSerial function built into PSQL but if you are using v9 or later, you might be able to create your own function.

PSQL 9.  

I think that I found the function:
TIMESTAMPADD ( SQL_TSI_DAY, "table name"."field.name", CONVERT('0001-01-01', SQL_TIMESTAMP) ) -1
