值java.sql.SQLException：ORA-00904(java.sql.SQLExcep

我得到这个下面exception-

java.sql.SQLException: ORA-00904: : invalid identifier
ORA-06512: at line 1

下面是我想execute-查询

public static final String DATABASE_TABLE = "LnPData";

public static final String CREATE_SQL = "DECLARE " +
"t_count INTEGER; " +
"v_sql VARCHAR2(1000) := 'create table " +DATABASE_TABLE + "(" +
"(ID number(10,0), " +
"CGUID VARCHAR(255), " + 
"PGUID VARCHAR(255), " + 
"SGUID VARCHAR(255), " + 
"USERID VARCHAR(255), " +
"ULOC VARCHAR(255), " +
"SLOC VARCHAR(255), " +
"PLOC VARCHAR(255), " +
"ALOC VARCHAR(255), " +
"SITEID VARCHAR(255), " +
"PRIMARY KEY ( ID ))'; " +
"BEGIN " +
"SELECT COUNT(*) " +
"INTO t_count " +
"FROM user_tables " +
"WHERE table_name = '" +DATABASE_TABLE + "'; " +

"IF t_count = 0 THEN " +
"EXECUTE IMMEDIATE v_sql; " +
"END IF; " +
"END; ";

在控制台是越来越原样打印

DECLARE t_count INTEGER; v_sql VARCHAR2(1000) := 'create table LnPData((ID number(10,0), CGUID VARCHAR(255), PGUID VARCHAR(255), SGUID VARCHAR(255), USERID VARCHAR(255), ULOC VARCHAR(255), SLOC VARCHAR(255), PLOC VARCHAR(255), ALOC VARCHAR(255), SITEID VARCHAR(255), PRIMARY KEY ( ID ))'; BEGIN SELECT COUNT(*) INTO t_count FROM user_tables WHERE table_name = 'LnPData'; IF t_count = 0 THEN EXECUTE IMMEDIATE v_sql; END IF; END; 

Answer 1:

更改

"v_sql VARCHAR2(1000) := 'create table " +DATABASE_TABLE + "(" +
"(ID number(10,0), " +

成

"v_sql VARCHAR2(1000) := 'create table " +DATABASE_TABLE +
"(ID number(10,0), " +

而且这是工作。 你只要有一个不正确支架。
