这是我的查询：
select * from table where fieldA in ( :1 )
该参数:1应该是一个字符串数组，我想使用 ocibindbypos 动态绑定它。我怎样才能做到这一点 ？当我尝试使用字符串类型绑定('1','2','3')时，它不起作用。我可以在文件 ocidfn.h 中看到：
/* input data types */
#define SQLT_CHR 1 /* (ORANET TYPE) character string */
#define SQLT_NUM 2 /* (ORANET TYPE) oracle numeric */
#define SQLT_INT 3 /* (ORANET TYPE) integer */
#define SQLT_FLT 4 /* (ORANET TYPE) Floating point number */
#define SQLT_STR 5 /* zero terminated string */
#define SQLT_VNU 6 /* NUM with preceding length byte */
#define SQLT_PDN 7 /* (ORANET TYPE) Packed Decimal Numeric */
#define SQLT_LNG 8 /* long */
#define SQLT_VCS 9 /* Variable character string */
#define SQLT_NON 10 /* Null/empty PCC Descriptor entry */
#define SQLT_RID 11 /* rowid */
#define SQLT_DAT 12 /* date in oracle format */
#define SQLT_VBI 15 /* binary in VCS format */
#define SQLT_BIN 23 /* binary data(DTYBIN) */
#define SQLT_LBI 24 /* long binary */
#define SQLT_UIN 68 /* unsigned integer */
#define SQLT_SLS 91 /* Display sign leading separate */
#define SQLT_LVC 94 /* Longer longs (char) */

#define SQLT_LAB 105 /* label type */
#define SQLT_OSL 106 /* oslabel type */
#define SQLT_NTY 108 /* named object type */
#define SQLT_REF 110 /* ref type */
#define SQLT_CLOB 112 /* character lob */
#define SQLT_BLOB 113 /* binary lob */
#define SQLT_BFILEE 114 /* binary file lob */
#define SQLT_CFILEE 115 /* character file lob */
#define SQLT_RSET 116 /* result set type */
#define SQLT_NCO 122 /* named collection type (varray or nested table) */
#define SQLT_VST 155 /* OCIString type */
#define SQLT_ODT 156 /* OCIDate type */
/* datetimes and intervals */
#define SQLT_DATE 184 /* ANSI Date */
#define SQLT_TIME 185 /* TIME */
#define SQLT_TIME_TZ 186 /* TIME WITH TIME ZONE */
#define SQLT_TIMESTAMP 187 /* TIMESTAMP */
#define SQLT_TIMESTAMP_TZ 188 /* TIMESTAMP WITH TIME ZONE */
#define SQLT_INTERVAL_YM 189 /* INTERVAL YEAR TO MONTH */
#define SQLT_INTERVAL_DS 190 /* INTERVAL DAY TO SECOND */
#define SQLT_TIMESTAMP_LTZ 232 /* TIMESTAMP WITH LOCAL TZ */
我应该使用哪一个？
