SQL 命令根据年初至今或两个日期之间的已售库存更新再订购水平和数量

Question

I tried to put the following into my Database Utility in IQ Retail, but it did not work.

update Stock
set MIN_LVL=UnitsYearToDate/5
set ORD_QUANT=UnitsYearToDate/5*3
where (only using one of the following)
REGULAR_SU='xxx'
or
SUBDEPARTM='xxx'
or
CODE between 'xxx' and 'xxx'

I get this error

"DBISAM Engine Error # 11949 SQL parsing error - Expected end of statement but instead found set in UPDATE SQL statement at line 3, column 1"

I have no programming knowledge, I am just trying to self help because of my remote location. Any advice on how I can update minimum order levels and order quantities in specific batches for about 12000 stock items would be appreciated.

I am using the packaged database utility in IQ Retail software.

Answer 1

Try below - you don't need to define set multiple times, just use one set and define multiple columns using comma (,)

update Stock set MIN_LVL=UnitsYearToDate/5,ORD_QUANT=UnitsYearToDate/5*3 
where REGULAR_SU='xxx' or SUBDEPARTM='xxx' or CODE between 'xxx' and 'xxx'

Answer 2

Your syntax is worng. Multiple SET must be separated by comma:

update Stock
set MIN_LVL=UnitsYearToDate/5, ORD_QUANT=UnitsYearToDate/5*3
where 
REGULAR_SU='xxx'
or
SUBDEPARTM='xxx'
or
CODE between 'xxx' and 'xxx'

Answer 3

As others have stated, the syntax is incorrect and when you have multiple SET you will need to separate them with a comma. DBISAM order of execution can be different you will need to note that as well. Refer to this documentation for an UPDATE Statement

Try this code

UPDATE Stock SET MIN_LVL = 2, ORD_QUAN = 3 FROM Stock WHERE SUBDEPARTM = '0002';
