<pre>public interface <span class="typeNameLabel">SqlValidator</span></pre>
<div class="block">Validates the parse tree of a SQL statement, and provides semantic
information about the parse tree.
<p>To create an instance of the default validator implementation, call
<a href="../../../../../org/apache/calcite/sql/validate/SqlValidatorUtil.html#newValidator-org.apache.calcite.sql.SqlOperatorTable-org.apache.calcite.sql.validate.SqlValidatorCatalogReader-org.apache.calcite.rel.type.RelDataTypeFactory-org.apache.calcite.sql.validate.SqlConformance-"><code>SqlValidatorUtil.newValidator(org.apache.calcite.sql.SqlOperatorTable, org.apache.calcite.sql.validate.SqlValidatorCatalogReader, org.apache.calcite.rel.type.RelDataTypeFactory, org.apache.calcite.sql.validate.SqlConformance)</code></a>.
<h2>Visitor pattern</h2>
<p>The validator interface is an instance of the
<a href="../../../../../org/apache/calcite/util/Glossary.html#VISITOR_PATTERN"><code>visitor pattern</code></a>.
Implementations
of the <a href="../../../../../org/apache/calcite/sql/SqlNode.html#validate-org.apache.calcite.sql.validate.SqlValidator-org.apache.calcite.sql.validate.SqlValidatorScope-"><code>SqlNode.validate(org.apache.calcite.sql.validate.SqlValidator, org.apache.calcite.sql.validate.SqlValidatorScope)</code></a> method call the <code>validateXxx</code>
method appropriate to the kind of node:
<ul>
<li><a href="../../../../../org/apache/calcite/sql/SqlLiteral.html#validate-org.apache.calcite.sql.validate.SqlValidator-org.apache.calcite.sql.validate.SqlValidatorScope-"><code>SqlLiteral.validate(SqlValidator, SqlValidatorScope)</code></a>
calls
<a href="../../../../../org/apache/calcite/sql/validate/SqlValidator.html#validateLiteral-org.apache.calcite.sql.SqlLiteral-"><code>validateLiteral(org.apache.calcite.sql.SqlLiteral)</code></a>;
<li><a href="../../../../../org/apache/calcite/sql/SqlCall.html#validate-org.apache.calcite.sql.validate.SqlValidator-org.apache.calcite.sql.validate.SqlValidatorScope-"><code>SqlCall.validate(SqlValidator, SqlValidatorScope)</code></a>
calls
<a href="../../../../../org/apache/calcite/sql/validate/SqlValidator.html#validateCall-org.apache.calcite.sql.SqlCall-org.apache.calcite.sql.validate.SqlValidatorScope-"><code>validateCall(SqlCall, SqlValidatorScope)</code></a>;
<li>and so forth.</ul>
<p>The <a href="../../../../../org/apache/calcite/sql/SqlNode.html#validateExpr-org.apache.calcite.sql.validate.SqlValidator-org.apache.calcite.sql.validate.SqlValidatorScope-"><code>SqlNode.validateExpr(SqlValidator, SqlValidatorScope)</code></a> method
is as <a href="../../../../../org/apache/calcite/sql/SqlNode.html#validate-org.apache.calcite.sql.validate.SqlValidator-org.apache.calcite.sql.validate.SqlValidatorScope-"><code>SqlNode.validate(SqlValidator, SqlValidatorScope)</code></a> but is called
when the node is known to be a scalar expression.
<h2>Scopes and namespaces</h2>
<p>In order to resolve names to objects, the validator builds a map of the
structure of the query. This map consists of two types of objects. A
<a href="../../../../../org/apache/calcite/sql/validate/SqlValidatorScope.html" title="org.apache.calcite.sql.validate中的接口"><code>SqlValidatorScope</code></a> describes the tables and columns accessible at a
particular point in the query; and a <a href="../../../../../org/apache/calcite/sql/validate/SqlValidatorNamespace.html" title="org.apache.calcite.sql.validate中的接口"><code>SqlValidatorNamespace</code></a> is a
description of a data source used in a query.
<p>There are different kinds of namespace for different parts of the query.
for example <a href="../../../../../org/apache/calcite/sql/validate/IdentifierNamespace.html" title="org.apache.calcite.sql.validate中的类"><code>IdentifierNamespace</code></a> for table names,
<a href="../../../../../org/apache/calcite/sql/validate/SelectNamespace.html" title="org.apache.calcite.sql.validate中的类"><code>SelectNamespace</code></a> for SELECT queries,
<a href="../../../../../org/apache/calcite/sql/validate/SetopNamespace.html" title="org.apache.calcite.sql.validate中的类"><code>SetopNamespace</code></a> for UNION, EXCEPT
and INTERSECT. A validator is allowed to wrap namespaces in other objects
which implement <a href="../../../../../org/apache/calcite/sql/validate/SqlValidatorNamespace.html" title="org.apache.calcite.sql.validate中的接口"><code>SqlValidatorNamespace</code></a>, so don't try to cast your
namespace or use <code>instanceof</code>; use
<a href="../../../../../org/apache/calcite/sql/validate/SqlValidatorNamespace.html#unwrap-java.lang.Class-"><code>SqlValidatorNamespace.unwrap(Class)</code></a> and
<a href="../../../../../org/apache/calcite/sql/validate/SqlValidatorNamespace.html#isWrapperFor-java.lang.Class-"><code>SqlValidatorNamespace.isWrapperFor(Class)</code></a> instead.</p>
<p>The validator builds the map by making a quick scan over the query when
the root <a href="../../../../../org/apache/calcite/sql/SqlNode.html" title="org.apache.calcite.sql中的类"><code>SqlNode</code></a> is first provided. Thereafter, it supplies the
correct scope or namespace object when it calls validation methods.</p>
<p>The methods <a href="../../../../../org/apache/calcite/sql/validate/SqlValidator.html#getSelectScope-org.apache.calcite.sql.SqlSelect-"><code>getSelectScope(org.apache.calcite.sql.SqlSelect)</code></a>, <a href="../../../../../org/apache/calcite/sql/validate/SqlValidator.html#getFromScope-org.apache.calcite.sql.SqlSelect-"><code>getFromScope(org.apache.calcite.sql.SqlSelect)</code></a>,
<a href="../../../../../org/apache/calcite/sql/validate/SqlValidator.html#getWhereScope-org.apache.calcite.sql.SqlSelect-"><code>getWhereScope(org.apache.calcite.sql.SqlSelect)</code></a>, <a href="../../../../../org/apache/calcite/sql/validate/SqlValidator.html#getGroupScope-org.apache.calcite.sql.SqlSelect-"><code>getGroupScope(org.apache.calcite.sql.SqlSelect)</code></a>, <a href="../../../../../org/apache/calcite/sql/validate/SqlValidator.html#getHavingScope-org.apache.calcite.sql.SqlSelect-"><code>getHavingScope(org.apache.calcite.sql.SqlSelect)</code></a>,
<a href="../../../../../org/apache/calcite/sql/validate/SqlValidator.html#getOrderScope-org.apache.calcite.sql.SqlSelect-"><code>getOrderScope(org.apache.calcite.sql.SqlSelect)</code></a> and <a href="../../../../../org/apache/calcite/sql/validate/SqlValidator.html#getJoinScope-org.apache.calcite.sql.SqlNode-"><code>getJoinScope(org.apache.calcite.sql.SqlNode)</code></a> get the correct scope
to resolve
names in a particular clause of a SQL statement.</p></div>
