【问题描述】：

我的数据库中有以下字符串 (SnowFlake)

:display_redemption_mark: 0
:redeemable_properties: '1205,1206,1207,1208,1209,1210,1211,1212,1213,1214,1215,1216,1217,1218,1225,1227,1230,1231,1232,1239,1242,1244,1249,1250,1254,1281,1282,1283,1284,1285,1286,1287,1288,1289,1290,1291,1292,1293,1294,1296,1297,1240,1247,1255'
:redemption_meta_keys: ''
:max_redemptions_in_transaction: 0
:allow_multiple_redemption_on_item: false
:allow_qualifying_items_reused: false

我想提取 redeemable_properties 的值，在上面的例子中

1205,1206,1207,1208,1209,1210,1211,1212,1213,1214,1215,1216,1217,1218,1225,1227,1230,1231,1232,1239,1242,1244,1249,1250,1254,1281,1282,1283,1284,1285,1286,1287,1288,1289,1290,1291,1292,1293,1294,1296,1297,1240,1247,1255

我想要排除单引号和双引号因为整个值是一个字符串并存储在表的一列中。我正在创建一个包含提取值的新列。

以下是 redeemable_properties 可能具有的值

:redeemable_properties: 1,2,3,early_access,donatable

你能试试这个吗？

select trim( regexp_substr( your_column, '.*:redeemable_properties:([^:]*):',1,1,'e' ), '''" ' ) from your_table;
