Logical operators query data using logic applied to the results of field-level operators. Common logical operators includeand()where all operators must be true, andor()where at least one of the operators must be true. The following example uses theFilters.and()method to match documents where th...
To avoid an SQL injection vulnerability, extra must not contain untrusted user input as these values are interpolated into the SQL string rather than passed as query parameters, where the database driver would escape them. The function, template, and arg_joiner keywords can be used to replace ...
values returned by the query. Using late binding you can access these directly.Figure 8contains an example of how to create a sorted version of the original query. Since you are using a Comparer instead of an order by statement, this will be a lazy evaluation and will perform well...
The following objects must be defined before you access the page: Component string&DYN_QUERYNAME; Component number&DYN_SEQNUM; ComponentPT_CUBQUERYCHUNK:QueryChunker &cChunker; These values hold the query name and the unique sequence number. Remember that the sequence number is used to uniquely ...

When using LINQ to query nongeneric IEnumerable collections such as ArrayList, you must explicitly declare the type of the range variable to reflect the specific type of the objects in the collection. If you have an ArrayList of Student objects, your from clause should look like this: C# Copy...

If the query compares multiple values of the same abstract schema type, then theFROMclause must declare multiple identification variables for the abstract schema: FROM Player p1, Player p2 For a sample of such a query, seeComparison Operators. ...
To insert an empty string into a Microsoft Access table using the SequelLink ODBC Socket or SequelLink Access driver, the CFSQLType attribute must specify CF_SQL_LONGVARCHAR.The following table shows the mapping of ColdFusion SQL data types with JDBC SQL types and those of the listed database...
In contrast to the deferred execution of queries that produce a sequence of values, queries that return a singleton value are executed immediately. Some examples of singleton queries areAverage,Count,First, andMax. These execute immediately because the query must produce a sequence to calculate the...
