I am using SQL Server. The following query is working fine:
select *
from Users
where Users.Id = 1
but when I use
select *
from Users
where Users.Username = "User"
this does not work.
Error:
Invalid Column name

Use on quote instead of double quote
select * from Users where Users.Username = 'User'
text datatype has been deprecated, you need to change the datatype to VARCHAR(n)/NVARCHAR(n) as it depends on your data and your needs.

SQL Newbie here ...
Service_plan table has a record per customer with PKEY service_plan_id
SERVICE_PLAN_ID table keeps track of version changes with same PKEY
When I run this query [other selects omitted for brevity] in Oracle 10.2.0 iSQL command line, I get an error:
select S1.service_plan_id as TN,V1.VERSION_ID as Version
from Service_plan S1
inner join
(select distinct service_plan_id, max(VERSION_ID)
from SERVICE_PLAN_VERSION
where service_ID='COLL'
group by service_plan_id) as V1
on V1.SERVICE_PLAN_ID = S1.SERVICE_PLAN_ID
where S1.SERVICE_ID='COLL';
Error: missing key word on the "group by service_plan_id) as V1" line - it points to the "as" as the problem.
Any thoughts? Thx
Tried the standalone select and it works fine

select *
from table_name
where charindex(dest_mail,'abc#mail.com') >0
In the above query dest_mail is a column, but there is another entry in the table, which is 'bc#mail.com'. When I try to execute the above query, I'm getting two results
1.abc#mail.com
2.bc#mail.com
How to get exact 'abc#mail.com'?
Have you considered =?
where dest_mail = 'abc#mail.com'
Also, charindex() is not very colloquial SQL for this purpose; = is a built-in standard operator (charindex() is not standard). And a bonus to = is that it allows the optimizer to take advantage of indexes and partitions.

SELECT INDIVIDUAL.INV_FNAME,
INDIVIDUAL.INV_LNAME,
INDIVIDUAL.INV_IC_NUM,
CUSTOMER.MEMBER_LEVEL,
CUSTOMER.MEMBER_POINT_BALANCE,
CUSTOMER.MEMBER_DISCOUNT_RATE,
PROGRAM_USER.USER_CONTACT_NUM,
PROGRAM_USER.USER_ADDRESS,
PROGRAM_USER.USER_CITY,
PROGRAM_USER.USER_STATE,
PROGRAM_USER.USER_ZIP_CODE,
PROGRAM_USER.USER_COUNTRY,
PROGRAM_USER.USER_EMAIL
FROM PROGRAM_USER,CUSTOMER,INDIVIDUAL
WHERE USER_ID = ‘san’;
In your query only USER_ID column in the where condition is not specified with a table name. I guess USER_ID is there in multiple table. Try the where condition with proper table name
SELECT INDIVIDUAL.INV_FNAME,
INDIVIDUAL.INV_LNAME,
INDIVIDUAL.INV_IC_NUM,
CUSTOMER.MEMBER_LEVEL,
CUSTOMER.MEMBER_POINT_BALANCE,
CUSTOMER.MEMBER_DISCOUNT_RATE,
PROGRAM_USER.USER_CONTACT_NUM,
PROGRAM_USER.USER_ADDRESS,
PROGRAM_USER.USER_CITY,
PROGRAM_USER.USER_STATE,
PROGRAM_USER.USER_ZIP_CODE,
PROGRAM_USER.USER_COUNTRY,
PROGRAM_USER.USER_EMAIL
FROM PROGRAM_USER,CUSTOMER,INDIVIDUAL
WHERE PROGRAM_USER.USER_ID = ‘san’;
Also like #HoneyBadger comment you need to specify the join between the tables

It should be:
CHARINDEX('.\',si.SoftwareImage)
