SQL code in Access says error in FROM clause
SELECT p.Name, p.Age, MAX(COUNT(m.winTeam_ID) / (COUNT(m.winTeam_ID) + COUNT(m.lossTeam_ID))) FROM Players AS p INNER JOIN Teams AS t ON t.ID = p.Team_ID INNER JOIN Matches AS m ON m.Team_ID = t.ID GROUP BY p.Name, p.Age;
I can suggest the following query:
SELECT TOP 1 p.Name, p.Age, COUNT(m.winTeam_ID) / (COUNT(m.winTeam_ID) + COUNT(m.lossTeam_ID)) FROM (Players AS p INNER JOIN Teams AS t ON t.ID = p.Team_ID) INNER JOIN Matches AS m ON m.Team_ID = t.ID GROUP BY p.Name, p.Age ORDER BY COUNT(m.winTeam_ID) / (COUNT(m.winTeam_ID) + COUNT(m.lossTeam_ID)) DESC;
This fixes the syntax problem with your joins. It also interprets the
MAX as meaning that you want the record with the maximum ratio of counts. In this case, we can use
TOP 1 along with
ORDER BY to identify this max record.
Error when you run a query in Access, Syntax error in query expression ' Table Name . PMonth': Missing operator. If the field name only contains one character, such as "1", you these are the requirements that we have to use SQL to code and we have to build in a check on the table. I can't find a helpful answer -- CREATE TABLE data ( data_Name VARCHAR(10) UNIQUE, data_totals INT, CONSTRAINT [data_totals_test] CHECK (data_totals between 1 and 5 ) );
MS Access requires strange parentheses when you have more than one
join. In addition,
MAX(COUNT(m.winTeam_ID)) doesn't make sense. I don't know what you are trying to calculate in the
SELECT. Perhaps this does what you want:
SELECT p.Name, p.Age, COUNT(m.winTeam_ID) / (COUNT(m.winTeam_ID) + COUNT(m.lossTeam_ID))) FROM (Players AS p INNER JOIN Teams AS t ON t.ID = p.Team_ID ) INNER JOIN Matches AS m ON m.Team_ID = t.ID GROUP BY p.Name, p.Age;
[Solved] 'Syntax error in from clause.' VB.NET - access, As the error says, your DELETE syntax is incorrect. Your code is also vulnerable to SQL Injection[^]. NEVER use string concatenation to build a The “Type mismatch in expression” error indicates that Access cannot match an input value to the data type it expects for the value. For example, if you give Access a text string when it is expecting a number, you receive a data type mismatch error. Let us look at some situations where this error can occur.
I think your
Matches table shouldn't have a
Team_ID And instead you have
And also you want to query players of a team with - something like - the best win-rate.
If so, Use a query like this - tested on SQL Server only -:
select p.Age, p.Name, ts.rate from Players p join (select top(1) -- sub-query will return just first record t.ID , sum(case when (t.ID = winTeam_ID) then 1 else 0 end) as wins , sum(case when (t.ID = lossTeam_ID) then 1 else 0 end) as losses , sum(case when (t.ID = winTeam_ID) then 1.0 else 0.0 end) / (sum(case when (t.ID = winTeam_ID) then 1.0 else 0.0 end) + sum(case when (t.ID = lossTeam_ID) then 1.0 else 0.0 end)) as rate from Teams as t left join Matches as m on t.ID = m.winTeam_ID or t.ID = lossTeam_ID group by t.ID order by rate desc -- This will make max rate as first ) as ts -- Team stats calculated in this sub-query on p.Team_ID = ts.ID;
SQL code in Access says error in FROM clause, SQL code in Access says error in FROM clause. syntax error (missing operator) in query expression access error in access query syntax error in field definition Access absolutely requires parentheses in the FROM clause of any query which includes more that one join. If you have Access available, create and test a new query in the query designer. One of the reasons the designer is useful is that it knows the rules for parentheses which keep the db engine happy. Start with a query similar to this.
Union query - syntax error in from clause, What does the error message say? Are you absolutely certain that the table names in your SQL are spelled exactly as they appear on the This article is the fourth in a series of articles about subqueries, and we will be discussing how to use a subquery in the FROM clause. In other articles, it covered the uses in other clauses. All the examples for this lesson are based on Microsoft SQL Server Management Studio and the AdventureWorks2012 database.
Syntax Error in FROM Clause – Daily Dose of Excel, I don't typically use the query wizard, but I got the same error message in required to enclose the table name in brackets in any SQL statements I write. Why do I have an ODBC driver for Access if I don't have Access installed? ADO is better for heterogeneous work in say .asp web pages where you SQL Keyword errors. SQL keyword errors occur when one of the words that the SQL query language reserves for its commands and clauses is misspelled. For example, writing “UPDTE” instead of “UPDATE” will produce this type of error. In this example, the keyword “TABLE” is misspelled: As shown in the image above, not only the word “TBLE” is highlighted, but also the words around it.
