The values that are used with the BETWEEN operator are included in the range, meaning that the lower bound includes the value of 10 and the upper bound includes the value of 200. The use of the BETWEEN operator should make your query more easy to read, especially if multiple query conditio...
Halt the procedure successfully, meaning the theorem is true, when a contradiction occurs—that is, when an empty clause (generally represented by □) is produced. Otherwise, if an empty clause cannot be produced, the theorem is false. After step 1, our axiom set is ¬A∨ B ∨ C, A ...
Sometimes rows with different schema are mapped to a single physical table, with multipurpose columns such asntext1, ntext2, bigint1, bigint2storing semantically unrelated data. Typically, there is also a special-purposerowtypecolumn that defines what is the semantic meaning of the data stored ...
Meaning that the query took 4.5 seconds to execute (and this was only one continuation).To optimize this example query, avoid the use of UPPER in the filter. Instead, when documents are created or updated, the c.description values must be inserted in all uppercase characters. The query ...

Set-oriented processing, meaning pipelined execution of FLWOR clauses through operators, which operate on arrays of tuples and thus support known optimizations from relational database querying for implicit joins and aggregates.We're currently working on a Jupyter Notebook / Tutorial.Here...
