Method Detail

parseQuery

public static SqlNodeAndOptions parseQuery(String query,
                                           com.fasterxml.jackson.databind.JsonNode request)
                                    throws SqlCompilationException

Throws:

SqlCompilationException

setOptions

public static void setOptions(SqlNodeAndOptions sqlNodeAndOptions,
                              com.fasterxml.jackson.databind.JsonNode jsonRequest)

Sets extra options for the given query.

getIdentifierExpression

public static Expression getIdentifierExpression(String identifier)

getLiteralExpression

public static Expression getLiteralExpression(org.apache.calcite.sql.SqlLiteral node)

createNewLiteralExpression

public static Expression createNewLiteralExpression()

getLiteralExpression

public static Expression getLiteralExpression(boolean value)

getLiteralExpression

public static Expression getLiteralExpression(long value)

getLiteralExpression

public static Expression getLiteralExpression(double value)

getLiteralExpression

public static Expression getLiteralExpression(String value)

getLiteralExpression

public static Expression getLiteralExpression(byte[] value)

getLiteralExpression

public static Expression getLiteralExpression(Object object)

getFunctionExpression

public static Expression getFunctionExpression(String canonicalName)

canonicalizeFunctionName

public static String canonicalizeFunctionName(String functionName)

Converts the function name into its canonical form.

canonicalizeFunctionNamePreservingSpecialKey

public static String canonicalizeFunctionNamePreservingSpecialKey(String functionName)

Converts the function name into its canonical form, but preserving the special keys. - Keep FilterKind.name() as is because we need to read the FilterKind via FilterKind.valueOf(). - Keep ST_Distance as is because we use exact match when applying geo-spatial index up to release 0.10.0. TODO: Remove the ST_Distance special handling after releasing 0.11.0.

prettyPrint

public static String prettyPrint(Expression expression)

getTableName

public static String getTableName(PinotQuery pinotQuery)

getOptionsFromJson

public static Map<String,String> getOptionsFromJson(com.fasterxml.jackson.databind.JsonNode request,
                                                          String optionsKey)

getOptionsFromString

public static Map<String,String> getOptionsFromString(String optionStr)
