join is a qualifier stating if several tables are to be joined together into one. Field names and table names
must be put within quotes if they contain blank spaces or letters from the national character sets. When the
script is automatically generated by QlikView, the quotation mark used is the one preferred by the ODBC
driver specified in the data source definition of the data source in the Connect (page 227) statement.
Furthermore, several SELECT statements can sometimes be concatenated into one through the use of a
union operator:
selectstatement union selectstatement
The SELECT statement is interpreted by the ODBC driver, so deviations from the general SQL syntax
might occur depending on the capabilities of the ODBC drivers, e.g.
as is sometimes not allowed, i.e. aliasname must follow immediately after fieldname.
as is sometimes compulsory if an aliasname is used.
distinct, as, where, group by, order by, or union is sometimes not supported.
The ODBC driver sometimes does not accept all the different quotation marks listed above.
Note!
This is not a complete description of the SQL SELECT statement! E.g. SELECT statements can be nested,
several joins can be made in one SELECT statement, the number of functions allowed in expressions is
sometimes very large, etc.
Examples:
SELECT * FROM `Categories`;
SELECT `Category ID`, `Category Name` FROM `Categories`;
SELECT `Order ID`, `Product ID`,
`Unit Price` * Quantity * (1-Discount) as NetSales
FROM `Order Details`;
SELECT `Order Details`.`Order ID`,
Sum(`Order Details`.`Unit Price` * `Order Details`.Quantity) as
`Result`
FROM `Order Details`, Orders
where Orders.`Order ID` = `Order Details`.`Order ID`
group by `Order Details`.`Order ID`;

Semantic
Tables containing relations between objects can be loaded through a semantic prefix.
The syntax is:
semantic( loadstatement | selectstatement)
Examples:
Semantic Load * from abc.csv;
Semantic Select Object1, Relation, Object2, InverseRelation from
table1;
