三、SQLserver中字段名和保留字冲突的解决 只需要用[]把字段名括起来这样在select、insert、update、delete等语句中都不会出现语法错误 四、Oracle中字段名和保留字冲突的解决 (1)官方文档说明 Reserved words and keywordsare identifiers that have special meaning in PL/SQL. You cannot use reserved words as ordinary user-defined identifiers. You can use them as quoted user-defined identifiers, but it is not recommended. For more information, seeQuotedUser-Defined Identifiers. You can use keywords as ordinary user-defined identifiers,but it is not recommended. 译文 保留字和keywordsare标识符在PL / SQL的特殊意义。 不能使用保留字作为普通用户定义标识符。您可以使用它们作为引用的用户定义标识符但不推荐使用。更多信息见“quoteduser定义标识符”。 您可以使用关键字作为普通用户定义的标识符但不推荐使用。
(2)不能直接使用保留字作为用户定义的变量但加上双引号就使用。 如 create tale int id varchar(10), name varchar(10), primary key id);
出现错误int是关键字 create table int id varchar(10), name varchar(10), primary key id); 这样就正确 (3)保留字和关键字 保留字 Begins with:Reserved Words A ALL, ALTER, AND, ANY, AS, ASC, AT B BEGIN, BETWEEN, BY C CASE, CHECK, CLUSTERS, CLUSTER, COLAUTH, COLUMNS, COMPRESS, CONNECT, CRASH, CREATE, CURSOR D DECLARE, DEFAULT, DESC, DISTINCT, DROP E ELSE, END, EXCEPTION, EXCLUSIVE F FETCH, FOR, FROM, FUNCTION G GOTO, GRANT, GROUP H HAVING I IDENTIFIED, IF, IN, INDEX, INDEXES, INSERT, INTERSECT, INTO, IS L LIKE, LOCK M MINUS, MODE N NOCOMPRESS, NOT, NOWAIT, NULL O OF, ON, OPTION, OR, ORDER, OVERLAPS P PROCEDURE, PUBLIC R RESOURCE, REVOKE S SELECT, SHARE, SIZE, SQL, START, SUBTYPE T TABAUTH, TABLE, THEN, TO, TYPE U UNION, UNIQUE, UPDATE V VALUES, VIEW, VIEWS W WHEN, WHERE, WITH 关键字 Begins with:Keywords A A, ADD, AGENT, AGGREGATE, ARRAY, ATTRIBUTE, AUTHID, AVG B BFILE_BASE, BINARY, BLOB_BASE, BLOCK, BODY, BOTH, BOUND, BULK, BYTE C C, CALL, CALLING, CASCADE, CHAR, CHAR_BASE, CHARACTER, CHARSET, CHARSETFORM, CHARSETID, CLOB_BASE, CLOSE, COLLECT, COMMENT, COMMIT, COMMITTED, COMPILED, CONSTANT, CONSTRUCTOR, CONTEXT, CONTINUE, CONVERT, COUNT, CURRENT, CUSTOMDATUM D DANGLING, DATA, DATE, DATE_BASE, DAY, DEFINE, DELETE, DETERMINISTIC, DOUBLE, DURATION E ELEMENT, ELSIF, EMPTY, ESCAPE, EXCEPT, EXCEPTIONS, EXECUTE, EXISTS, EXIT, EXTERNAL F FINAL, FIXED, FLOAT, FORALL, FORCE G GENERAL H HASH, HEAP, HIDDEN, HOUR I IMMEDIATE, INCLUDING, INDICATOR, INDICES, INFINITE, INSTANTIABLE, INT, INTERFACE, INTERVAL, INVALIDATE, ISOLATION J Java L LANGUAGE, LARGE, LEADING, LENGTH, LEVEL, LIBRARY, LIKE2, LIKE4, LIKEC, LIMIT, LIMITED, LOCAL, LONG, LOOP M MAP, MAX, MAXLEN, MEMBER, MERGE, MIN, MINUTE, MOD, MODIFY, MONTH, MULTISET N NAME, NAN, NATIONAL, NATIVE, NCHAR, NEW, NOCOPY, NUMBER_BASE O OBJECT, OCICOLL, OCIDATE, OCIDATETIME, OCIDURATION, OCIINTERVAL, OCILOBLOCATOR, OCINUMBER, OCIRAW, OCIREF, OCIREFCURSOR, OCIROWID, OCISTRING, OCITYPE, OLD, ONLY, OPAQUE, OPEN, OPERATOR, Oracle, ORADATA, ORGANIZATION, ORLANY, ORLVARY, OTHERS, OUT, OVERRIDING P PACKAGE, PARALLEL_ENABLE, PARAMETER, PARAMETERS, PARENT, PARTITION, PASCAL, PIPE, PIPELINED, PRAGMA, PRECISION, PRIOR, PRIVATE R RAISE, RANGE, RAW, READ, RECORD, REF, REFERENCE, RELIES_ON, REM, REMAINDER, RENAME, RESULT, RESULT_CACHE, RETURN, RETURNING, REVERSE, ROLLBACK, ROW S SAMPLE, SAVE, SAVEPOINT, SB1, SB2, SB4, SECOND, SEGMENT, SELF, SEPARATE, SEQUENCE, SERIALIZABLE, SET, SHORT, SIZE_T, SOME, SPARSE, SQLCODE, SQLDATA, SQLNAME, SQLSTATE, STANDARD, STATIC, STDDEV, STORED, STRING, STRUCT, STYLE, SUBMULTISET, SUBPARTITION, SUBSTITUTABLE, SUM, SYNONYM T TDO, THE, TIME, TIMESTAMP, TIMEZONE_ABBR, TIMEZONE_HOUR, TIMEZONE_MINUTE, TIMEZONE_REGION, TRAILING, TRANSACTION, TRANSACTIONAL, TRUSTED U UB1, UB2, UB4, UNDER, UNSIGNED, UNTRUSTED, USE, USING V VALIST, VALUE, VARIABLE, VARIANCE, VARRAY, VARYING, VOID W WHILE, WORK, WRAPPED, WRITE Y YEAR Z ZONE
