| <div class="block">A <code>SqlOperator</code> is a type of node in a SQL parse tree (it is NOT a |
| node in a SQL parse tree). It includes functions, operators such as '=', and |
| syntactic constructs such as 'case' statements. Operators may represent |
| query-level expressions (e.g. <a href="../../../../org/apache/calcite/sql/SqlSelectOperator.html" title="org.apache.calcite.sql中的类"><code>SqlSelectOperator</code></a> or row-level |
| expressions (e.g. <a href="../../../../org/apache/calcite/sql/fun/SqlBetweenOperator.html" title="org.apache.calcite.sql.fun中的类"><code>SqlBetweenOperator</code></a>. |
| |
| <p>Operators have <em>formal operands</em>, meaning ordered (and optionally |
| named) placeholders for the values they operate on. For example, the division |
| operator takes two operands; the first is the numerator and the second is the |
| denominator. In the context of subclass <a href="../../../../org/apache/calcite/sql/SqlFunction.html" title="org.apache.calcite.sql中的类"><code>SqlFunction</code></a>, formal operands |
| are referred to as <em>parameters</em>. |
| |
| <p>When an operator is instantiated via a <a href="../../../../org/apache/calcite/sql/SqlCall.html" title="org.apache.calcite.sql中的类"><code>SqlCall</code></a>, it is supplied |
| with <em>actual operands</em>. For example, in the expression <code>3 / |
| 5</code>, the literal expression <code>3</code> is the actual operand |
| corresponding to the numerator, and <code>5</code> is the actual operand |
| corresponding to the denominator. In the context of SqlFunction, actual |
| operands are referred to as <em>arguments</em> |
| |
| <p>In many cases, the formal/actual distinction is clear from context, in |
| which case we drop these qualifiers.</div> |
