StrToFloat converts a string to a float64 at the best-effort.

adjustYear adjusts year according to y. See https://dev.mysql.com/doc/refman/5.7/en/two-digit-years.html

check whether t matches valid Time format. If allowZeroInDate is false, it returns ErrZeroDate when month or day is zero. FIXME: See https://dev.mysql

GetBytes gets bytes value.

GetFloat32 gets float32 value.

GetMyDecimal returns the MyDecimal value with the colIdx.

MemoryUsage returns the total memory usage of a Chunk in B. We ignore the size of column.length and column.nullCount since they have little effect of

MulUint64 multiplies uint64 a and b and returns uint64 if no overflow error.

NewString copies a byte slice into the arena and returns it as a string. If the arena is full, it returns a traditional go string.

NewWhere creates a WHERE or HAVING clause out of a Expr. If the expression is nil, it returns nil.

NumChunks returns the number of chunks in the List.

Instructions for creating new types: If a type needs to satisfy an interface, declare that function along with that interface. This will help users id

SetBytes sets bytes value to datum.

SetMysqlTime sets types.Time value

SetValue sets any kind of value.

SpaceLeft returns the amount of space left in the arena.

ToViewName returns a TableName acceptable for use as a VIEW. VIEW names are always lowercase, so ToViewName lowercasese the name. Databases are case-s

addFixedLenColumn adds a fixed length column with elemLen and initial data capacity.

rebuild merges the old and the modified JSON into a new BinaryJSON

AppendBytes appends a bytes value to the chunk.

AppendWarning appends a warning.

BytesConsumed returns the consumed memory usage value in bytes.

ConvertIntToUint converts an int value to an uint value.

DecodeInt decodes value encoded by EncodeInt before. It returns the leftover un-decoded slice, decoded value if no error.

EncodeUint appends the encoded value to slice b and returns the appended slice. EncodeUint guarantees that the encoded value is in ascending order for

FromGoTime translates time.Time to mysql time internal representation.

GetChunk gets the Chunk by ChkIdx.
