Package org.apache.juneau.beanquery.sql

package org.apache.juneau.beanquery.sql

Shared JDBC BeanQueryContext plumbing for BeanQuery (design §5.3).

This package is the public API of the juneau-beanquery-sql module: SqlBeanQueryContext (built once: dialect, table, columns, guard, connection source), SqlBeanQuerySession (one connection per request, streaming cursors), dialect-agnostic WHERE assembly, parameter binding, and the SqlDialect hook. Dialects (for example the Postgres dialect in juneau-beanquery-postgres) live in their own modules. The query carrier and operator API stay in org.apache.juneau.commons.beanquery.

Class	Description
ColumnResolver	Maps a logical column name to its dialect-quoted SQL reference, for SqlSearchCompiler.
SearchSqlRenderer	The SQL callback an application supplies for a custom search operator (design §5.3) so a SQL context can render it into a WHERE clause.
SqlBeanQueryContext<T>	The shared JDBC BeanQueryContext: renders validated queries into SQL for a SqlDialect and runs them on a connection from a configured source.
SqlBeanQueryContext.Builder<T>	Builder for SqlBeanQueryContext.
SqlBeanQuerySession<T>	A BeanQuerySession on one JDBC connection.
SqlBeanQuerySession.Builder<T>	Builder for SqlBeanQuerySession.
SqlDialect	The SQL-generation strategy for a SQL BeanQueryContext: it quotes identifiers, renders each built-in $-operator into a dialect-correct predicate, and renders pagination.
SqlFragment	A parameterized SQL predicate fragment: a boolean SQL expression plus the ordered bind values its ? placeholders consume.
SqlRowMapper<T>	Turns the current ResultSet row into a bean, for BeanQuerySession.find(BeanQuery) and BeanQuerySession.stream(BeanQuery).
SqlSearchCompiler	Compiles a resolved Filter tree into a SQL WHERE predicate for a SqlDialect.
SqlStatement	A fully-rendered SQL statement: the text (with ? placeholders) plus its ordered bind values, and the selected column names in SELECT order.
