Method Summary

Modifier and Type	Method and Description
protected java.lang.String	asString(io.inversion.rql.Term term) Overridden to exclude rdbms style '%' wildcards that are not needed for cosmos sw and ew queries.
protected java.lang.String	asVariableName(int valuesPairIdx) Cosmos does not use "?" ansi sql style prepared statement vars, it uses named variables prefixed with '@'.

protected java.lang.String	printLimitClause(io.inversion.jdbc.SqlQuery.Parts parts, int offset, int limit) Both offset and limit are required per cosmos spec.
protected java.lang.String	toSql(boolean preparedStmt) Makes a few blanked tweaks to the sql created by the SqlQuery superclass to make it Cosmos compliant

CosmosSqlQuery

public CosmosSqlQuery(CosmosDb db,
                      io.inversion.Collection table,
                      java.util.List<io.inversion.rql.Term> terms)

Method Detail

createWhere

protected io.inversion.rql.Where createWhere()

Overrides:

createWhere in class io.inversion.rql.Query<io.inversion.jdbc.SqlQuery,CosmosDb,io.inversion.rql.Select<io.inversion.rql.Select<io.inversion.rql.Select,io.inversion.jdbc.SqlQuery>,io.inversion.jdbc.SqlQuery>,io.inversion.rql.From<io.inversion.rql.From<io.inversion.rql.From,io.inversion.jdbc.SqlQuery>,io.inversion.jdbc.SqlQuery>,io.inversion.rql.Where<io.inversion.rql.Where<io.inversion.rql.Where,io.inversion.jdbc.SqlQuery>,io.inversion.jdbc.SqlQuery>,io.inversion.rql.Group<io.inversion.rql.Group<io.inversion.rql.Group,io.inversion.jdbc.SqlQuery>,io.inversion.jdbc.SqlQuery>,io.inversion.rql.Order<io.inversion.rql.Order<io.inversion.rql.Order,io.inversion.jdbc.SqlQuery>,io.inversion.jdbc.SqlQuery>,io.inversion.rql.Page<io.inversion.rql.Page<io.inversion.rql.Page,io.inversion.jdbc.SqlQuery>,io.inversion.jdbc.SqlQuery>>

doSelect

public io.inversion.Results doSelect()
                              throws io.inversion.ApiException

Overrides:

doSelect in class io.inversion.jdbc.SqlQuery<CosmosDb>

Throws:

io.inversion.ApiException

toSql

protected java.lang.String toSql(boolean preparedStmt)

Makes a few blanked tweaks to the sql created by the SqlQuery superclass to make it Cosmos compliant

Replaces:

• SELECT "table".* FROM "table" -@gt; SELECT * FROM table
• "table"."column" -@gt; table["column"]

Overrides:

toSql in class io.inversion.jdbc.SqlQuery<CosmosDb>

See Also:

Cosmos Sql Query Select, Cosmos Sql Query - Quoted Property Accessor

getDefaultSorts

protected java.util.List<io.inversion.rql.Order.Sort> getDefaultSorts(io.inversion.jdbc.SqlQuery.Parts parts)

The inversion configured primary index should contain at least the document identifier and the partition key. If you don't supply a sort key on the query string that would default to adding two fields to the sort. If you did not configure cosmos to have a compound search index, that would fail...simply solution...if you did not supply a sort on the query string, just search by the "id" field.

Overrides:

getDefaultSorts in class io.inversion.jdbc.SqlQuery<CosmosDb>

printLimitClause

protected java.lang.String printLimitClause(io.inversion.jdbc.SqlQuery.Parts parts,
                                            int offset,
                                            int limit)

Both offset and limit are required per cosmos spec.

Overrides:

printLimitClause in class io.inversion.jdbc.SqlQuery<CosmosDb>

See Also:

Cosmos Offset and Limit

asVariableName

protected java.lang.String asVariableName(int valuesPairIdx)

Cosmos does not use "?" ansi sql style prepared statement vars, it uses named variables prefixed with '@'.

Overrides:

asVariableName in class io.inversion.jdbc.SqlQuery<CosmosDb>

asString

protected java.lang.String asString(io.inversion.rql.Term term)

Overridden to exclude rdbms style '%' wildcards that are not needed for cosmos sw and ew queries.

Overrides:

asString in class io.inversion.jdbc.SqlQuery<CosmosDb>

Returns:

the term as a string approperiate for use in a cosmos query

printExpression

protected java.lang.String printExpression(io.inversion.rql.Term term,
                                           java.util.List<java.lang.String> dynamicSqlChildText,
                                           java.util.List<java.lang.String> preparedStmtChildText)

Overrides:

printExpression in class io.inversion.jdbc.SqlQuery<CosmosDb>
