Class GeneratedJdbcData

java.lang.Object

io.helidon.data.jdbc.GeneratedJdbcData

public final class GeneratedJdbcData
extends Object

Methods used by generated Helidon Data JDBC repositories.

These methods form the compatibility boundary between JDBC repository code generation and the JDBC runtime. Application code uses JdbcClient directly.

Method Summary

Modifier and Type	Method	Description
static JdbcClient.Statement	bindNull(JdbcClient.Statement statement, int index, JDBCType type)	Binds SQL NULL for a generated declarative repository.
static JdbcClient.Statement	createGenerated(JdbcClient client, String sql, int parameterCount)	Creates a statement description for generated repository code that has already validated the positional JDBC SQL.

Method Details

createGenerated

public static JdbcClient.Statement createGenerated(JdbcClient client,
 String sql,
 int parameterCount)

Creates a statement description for generated repository code that has already validated the positional JDBC SQL.

The physical marker count is computed by the annotation processor. A statement from Helidon's JDBC provider avoids scanning static SQL and accessing the runtime marker count cache. An alternate provider uses its supported JdbcClient.create(String) operation.

Parameters:

client - JDBC client

sql - validated SQL containing positional JDBC markers

parameterCount - exact number of physical JDBC markers

Returns:

statement description

Throws:

NullPointerException - if the client or SQL is null

IllegalArgumentException - if the parameter count is negative or greater than the SQL text length

bindNull

public static JdbcClient.Statement bindNull(JdbcClient.Statement statement,
 int index,
 JDBCType type)

Binds SQL NULL for a generated declarative repository.

This method accepts only a statement created by Helidon's JDBC provider. Types that require a database type name are not supported.

Parameters:

statement - statement created by Helidon's JDBC provider

index - JDBC position starting at one

type - SQL type of the null value

Returns:

the statement

Throws:

NullPointerException - if the statement or type is null

IllegalArgumentException - if the position or type is invalid or the type requires a database type name

IllegalStateException - if a terminal operation has started

UnsupportedOperationException - if the statement was not created by Helidon's JDBC provider
