Change variable frequency
Finding data - find days where flow> and bod>
Variables with no data, delete from Vardesc
Database cleanup
Table Size Script

SQL Alerting on Triggers

4. Change Units
SELECT NAME, UNITS, 'mg/L' FROM VARDESC WHERE UNITS = 'mg/L’ UPDATE VARDESC SET UNITS='mg/L’ WHERE UNITS = 'mg/L’

5. Change variable frequency
SELECT NAME, VARTYPE FROM VARDESC,LOCATION WHERE VARDESC.LOCID=LOCATION.LOCID AND LVL1_ID=11 update VARDESC Set VARDESC.VARTYPE = ‘P' FROM VARDESC INNER JOIN LOCATION ON VARDESC.LOCID=LOCATION.LOCID WHERE LVL1_ID=11 IF THERE IS DATA IN THESE VARIABLES IT WILL BE ORPHANED (LOST). Use System Setup, Edit/View Variables to set variable type and be prompted for options of what to do with data.

6. Change Units
SELECT NAME, UNITS, 'mg/L' FROM VARDESC WHERE UNITS = 'mg/L’ UPDATE VARDESC SET UNITS='mg/L’ WHERE UNITS = 'mg/L’

7. Finding data - find days where flow> and bod>
SELECT F.DATESTAMP,F.CURVALUE as Flow, B.TEXTVALUE AS BOD FROM DATATBL F INNER JOIN DATATBL B ON F.DATESTAMP = B.DATESTAMP WHERE F.VARID = 1 AND B.VARID = 2 AND F.CURVALUE > 4 AND B.CURVALUE >300

8. Table Size Script

9. Database cleanup
SELECT ID,DIRNAME,FILENAME FROM FILES DELETE FROM FILES WHERE DIRNAME = 'CLIENT768’ To recover space use Shrink

10. Calcerrorlog in opsroot
