EncodeCompactBytes joins bytes with its length into a byte slice. It is more efficient in both space and time compare to EncodeBytes. Note that the en

EncodeComparableUvarint encodes uint64 into mem-comparable bytes.

EncodePassword converts plaintext password to hashed hex string.

EncodeUintDesc appends the encoded value to slice b and returns the appended slice. EncodeUintDesc guarantees that the encoded value is in descending

EncodeUvarint appends the encoded value to slice b and returns the appended slice. Note that the encoded result is not memcomparable.

GetInt64 gets the int64 value.

GetInt64 returns the int64 value with the colIdx.

GetInterface gets interface value.

GetJSON returns the JSON value with the colIdx.

GetMyDecimal returns the MyDecimal value with the colIdx.

GetRow gets the Row in the chunk with the row index.

GetRowCount gets the number of rows. Make sure it can pass `make race`.

GetSQLMode return the SQL mode of scanner.

GetSet returns the Set value with the colIdx.

GetTime returns the Time value with the colIdx. TODO: use Time structure directly.

GetType gets the evaluation type of the expression.

GetUint64 returns the uint64 value with the colIdx.

HasRealAsFloatMode detects if 'REAL_AS_FLOAT' mode is set in SQLMode

HasZerofillFlag checks if ZerofillFlag is set.

IndentFormatter returns a new Formatter which interprets %i and %u in the Format() formats string as indent and unindent commands. The commands can ne

IsBinaryStr returns a boolean indicating whether the field type is a binary string type.

IsEmpty returns true if TableName is nil or empty.

IsIntegral returns true if querypb.Type is an integral (signed/unsigned) that can be represented using up to 64 binary bits.

IsNegative returns whether a decimal is negative.

IsSigned returns true if querypb.Type is a signed integral.

IsTypeTime returns a boolean indicating whether the tp is time type like datetime, date or timestamp.

IsUnsigned returns true if querypb.Type is an unsigned integral. Caution: this is not the same as !IsSigned.

Len returns the number of values in the row.

Len returns the length.

Length gets the length of the datum.

MakeDatums creates datum slice from interfaces.

MakeString makes a VarBinary Value.
