```haskell Expr := LogicalExpr | NIL LogicalExpr := LogicalExpr BinaryLogicalOp LogicalExpr | UnaryLogicalOp LogicalExpr | "(" LogicalExpr ")" | SingleExpr BinaryLogicalOp := "&&" | "and" | "||" | "or" UnaryLogicalOp := "not" SingleExpr := TermExpr | CompareExpr TermExpr := IDENTIFIER "in" ConstantArray ConstantArray := "[" ConstantExpr { "," ConstantExpr } "]" ConstantExpr := Constant | ConstantExpr BinaryArithOp ConstantExpr | UnaryArithOp ConstantExpr Constant := INTERGER | FLOAT_NUMBER UnaryArithOp := "+" | "-" BinaryArithOp := "+" | "-" | "*" | "/" | "%" | "**" CompareExpr := IDENTIFIER CmpOp IDENTIFIER | IDENTIFIER CmpOp ConstantExpr | ConstantExpr CmpOp IDENTIFIER | ConstantExpr CmpOpRestricted IDENTIFIER CmpOpRestricted ConstantExpr CmpOpRestricted := "<" | "<=" CmpOp := ">" | ">=" | "<" | "<=" | "==" | "!=" INTERGER := 整数 FLOAT_NUM := 浮点数 IDENTIFIER := 列名 ``` Tips: 1. NIL represents an empty string, which means there is no Predicate for Expr. 2. Gramma is described by EBNF syntax,expressions that may be omitted or repeated are represented through curly braces `{...}`. After syntax analysis, following rules will be applied: 1. non-vector column must exist in Schema. 2. CompareExpr/TermExpr requires operand type matching. 3. CompareExpr between non-vector columns of different types is available 4. The modulo operation requires all operands to be integers. 5. Integer columns can only match integer operands. But float columns can match both integer and float operands. 6. In BinaryOp, the `and`/`&&` operator has higher priority than the `or`/`||` operator example: ```python A > 3 && A < 4 && (C > 5 || D < 6) 1 < A <= 2.0 + 3 - 4 * 5 / 6 % 7 ** 8 A == B FloatCol in [1.0, 2, 3.0] Int64Col in [1, 2, 3] or C != 6 ```
