Method Details

quote

protected String quote(String persistedName)

Description copied from class: AbstractSqlLikeQueryBuilder2

Quote a column name for the dialect.

Overrides:

quote in class AbstractSqlLikeQueryBuilder2

Parameters:

persistedName - The persisted name.

Returns:

The quoted name

getAliasName

public String getAliasName(PersistentEntity entity)

Description copied from class: AbstractSqlLikeQueryBuilder2

Get an alias name for the given entity.

Overrides:

getAliasName in class AbstractSqlLikeQueryBuilder2

Parameters:

entity - The entity

Returns:

The alias name

buildJoin

protected void buildJoin(String joinType,
 StringBuilder query,
 AbstractSqlLikeQueryBuilder2.QueryState queryState,
 PersistentAssociationPath joinAssociation,
 PersistentEntity associationOwner,
 String currentJoinAlias,
 String lastJoinAlias)

Description copied from class: AbstractSqlLikeQueryBuilder2

Build a join expression for the given alias, association, join type and builder.

Overrides:

buildJoin in class AbstractSqlLikeQueryBuilder2

Parameters:

joinType - The join type

query - The query builder

queryState - The state

joinAssociation - The association

associationOwner - The associated owner

currentJoinAlias - The current join alias

lastJoinAlias - The last join alias

buildAdditionalWhereClause

protected String buildAdditionalWhereClause(AbstractSqlLikeQueryBuilder2.QueryState queryState,
 io.micronaut.core.annotation.AnnotationMetadata annotationMetadata)

Description copied from class: AbstractSqlLikeQueryBuilder2

Builds additional where clause if there is Where annotation on the entity.

Overrides:

buildAdditionalWhereClause in class AbstractSqlLikeQueryBuilder2

Parameters:

queryState - the query state

annotationMetadata - the annotation metadata

Returns:

where clause if there was Where annotation on the entity (or joins for JPA implementation)

getTableName

protected String getTableName(PersistentEntity entity)

Description copied from class: AbstractSqlLikeQueryBuilder2

Get the table name for the given entity.

Specified by:

getTableName in class AbstractSqlLikeQueryBuilder2

Parameters:

entity - The entity

Returns:

The table name

getColumnName

protected String getColumnName(PersistentProperty persistentProperty)

Description copied from class: AbstractSqlLikeQueryBuilder2

Get the column name for the given property.

Specified by:

getColumnName in class AbstractSqlLikeQueryBuilder2

Parameters:

persistentProperty - The property

Returns:

The column name

createSelectionVisitor

protected AbstractSqlLikeQueryBuilder2.SqlSelectionVisitor createSelectionVisitor(io.micronaut.core.annotation.AnnotationMetadata annotationMetadata,
 AbstractSqlLikeQueryBuilder2.QueryState queryState,
 boolean distinct)

Description copied from class: AbstractSqlLikeQueryBuilder2

Create a selection visitor.

Overrides:

createSelectionVisitor in class AbstractSqlLikeQueryBuilder2

Parameters:

annotationMetadata - The annotation metadata

queryState - The query state

distinct - The distinct

Returns:

The visitor

computePropertyPaths

protected boolean computePropertyPaths()

Description copied from class: AbstractSqlLikeQueryBuilder2

Whether property path expressions require computation by the implementation. In a certain query dialects property paths are supported (such as JPA-QL where you can do select foo.bar) whilst for explicit SQL queries paths like this have to be computed into aliases / column name references.

Specified by:

computePropertyPaths in class AbstractSqlLikeQueryBuilder2

Returns:

True if property path computation is required.

isAliasForBatch

protected boolean isAliasForBatch(PersistentEntity persistentEntity,
 io.micronaut.core.annotation.AnnotationMetadata annotationMetadata)

Should aliases be used in batch statements.

Specified by:

isAliasForBatch in class AbstractSqlLikeQueryBuilder2

Parameters:

persistentEntity - the persistent entity

annotationMetadata - the method annotation metadata

Returns:

True if they should

formatParameter

protected AbstractSqlLikeQueryBuilder2.Placeholder formatParameter(int index)

Description copied from class: AbstractSqlLikeQueryBuilder2

Format the parameter at the given index.

Specified by:

formatParameter in class AbstractSqlLikeQueryBuilder2

Parameters:

index - The parameter

Returns:

The index

resolveJoinType

public String resolveJoinType(Join.Type jt)

Description copied from class: AbstractSqlLikeQueryBuilder2

Resolves the join type.

Specified by:

resolveJoinType in class AbstractSqlLikeQueryBuilder2

Parameters:

jt - The join type

Returns:

The join type.
