I have to take over old colleague's code and trying to understand this one SQL statement like below:
SELECT * FROM my_table WHERE date_key = '{0}'
Column date_keycontains int values such as 20220712, 20220120, etc.
The first guess is that SELECT statement filters for rows with 0 value in column date_key. However, when running that line of code, I receive this error :
SQL Error [100038] [22018]: Numeric value '{0}' is not recognized
What exactly does that line of code do?
That looks like a placeholder, replaced with an actual value in code when calling the query.

I am bit new this, can someone please help me to rectify this error. I am using sqllite:
The table name in the INSERT is wrong. And the column list must match the values list.
Try INSERT correct table name (target columns) Values (vales for each column).
Additionally if you omit any columns the insert will fail unless they have defaults.

I Couldn't find the value that has 'r' in the third position using LIKE operation in SQL.
could anyone help me, please?
I think it would be better to write something like this.
SELECT <column>, FROM <table> WHERE <condition> LIKE "__r%";
EDIT:
This is tested and functional for SQL Server and Oracle DBMSs.
SELECT * FROM <table> WHERE substring(<column>,3,1) = 'r'
Try this. This is using SQL Server which will yield the result you are looking for.
You want to get the r from 'scr' with position 3
Try this
SELECT * FROM Customers
WHERE CustomerName LIKE '__r%';
position is count of _.

Can someone help in coding a Access SQL statement/Query where I have a table with columns as shown with Ident No not primary
Ident_No-----Data1-----Data2-----Data3-----Data4-----Data5-----Data6
1----------------abc--------def---------null---------null--------null--------null
1----------------null--------null---------ghi----------jkl----------null--------null
1----------------null--------null---------null---------null--------mno--------pqr
Looking for result as shown below in the query result or a new table.
Ident_No-----Data1-----Data2-----Data3-----Data4-----Data5-----Data6
1----------------abc--------def---------ghi---------jkl--------mno--------pqr
Please Help Thanks in advance
You need to use group by and get the MAX() value for each column like
select `Ident_No`, max(`Data1`), max(`Data2`),
max(`Data3`), max(`Data4`), max(`Data5`), max(`Data6`)
from tbl9999
group by Ident_No

SELECT * FROM iveflownthat.messages WHERE from=1 OR to=1
Its keeps giving me errors. I checked to make sure that the fields, table, and database name are correct.
FROM and TO are keywords. You should use them like this: [FROM], [TO]
SELECT * FROM iveflownthat.messages WHERE [from]=1 OR [to]=1
"from" is a keyword in SQL. ENclose it in square brackets... " WHERE [from] = 1 OR [to] = 1 "
edit" What Alireza said...
You named your column 'from' which is a reserved word, so you're getting this error due to bad syntax.

Just for reference I am using SQL Azure.
I noticed when I am trying to select data from a table based on a license plate and the state of that plate I get no results back if the state is "IN". I realize the word "IN" is reserved in SQL server; however, I am containing that within quotes in my query. I currently am in testing phase and have only one record in the table which has a lisence plate 287YGB and state IN.
If I write my query as follows I get nothing back.
SELECT MakeModel, CitizenID, VehicleID FROM tblVehicles WHERE tblVehicles.Lisence = '287YGB' AND tblVehicles.PlateState = 'IN'
If I write my query this way I get back my result. But this is not good enough.
SELECT MakeModel, CitizenID, VehicleID FROM tblVehicles WHERE tblVehicles.Lisence = '287YGB'
And finally, if I write my query this way I get the only row in the table.
SELECT MakeModel, CitizenID, VehicleID FROM tblVehicles
From these tests I can see that the last where parameter is causing the problem. I am assuming it is due to the fact that the word "IN" is reserved. Is there a way around this?
Reserved words usually only cause problems if you're using them as field names, and in that case you need to wrap them with brackets ("[]") to eliminate the problem. I will amost guarantee you that your PlateState has some garbage in it, so you need to either trim it first (LTRIM(RTRIM(PlateState)) = 'IN') or use Like '%IN%' instead, and this will return the results you expect.
try this
SELECT MakeModel, CitizenID, VehicleID FROM tblVehicles WHERE tblVehicles.Lisence = '287YGB' AND LTRIM(RTRIM(tblVehicles.PlateState)) = 'IN'
