Re: What is the most efficient way to convert TIMESTAMP to BIGDATETIME?

Hello,

I have a couple of ways to do it:

CREATE INPUT WINDOW INWINDOW SCHEMA (
C_Integer integer,
C_Bigdatetime bigdatetime,
C_Timestamp timestamp,
C_Date date,
C_Long long,
C_String string,
C_Money2 money(2),
C_Money7 money(7),
C_Binary binary,
C_Float float)
PRIMARY KEY ( C_Integer ) ;

CREATE OUTPUT WINDOW OUTWINDOW SCHEMA (
Column1 integer ,
Column2 bigdatetime ,
Column3 bigdatetime ) PRIMARY KEY ( Column1 ) AS
SELECT
  IW.C_Integer as Column1,
  cast(bigdatetime,IW.C_Timestamp) as Column2,
  to_bigdatetime(to_long(IW.C_Timestamp)*1000) as Column3 FROM INWINDOW IW ;

You can test it with esp_subscribe:

%ESP_HOME%\bin\esp_subscribe -c studio:studio -p localhost:9786/default/p6 -s INWINDOW,OUTWINDOW

<INWINDOW ESP_OPS="i"  C_Integer="500" C_Bigdatetime="2014-05-10 04:10:26.609123" C_Timestamp="2014-05-10 04:10:26.609" C_Date="1970-01-01 19:12:12" C_Long="76" C_String="string" C_Money2="2.22" C_Money7="7.7777777" C_Binary="42696E6172792064617461" C_Float="3.141590"/>

<OUTWINDOW ESP_OPS="i"  Column1="500" Column2="2014-05-10 04:10:26.609000" Column3="2014-05-10 04:10:26.609000"/>
