需要 SQL 的正则表达式从长字符串中提取 substring

Question

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

我想提取上述情况下的redeemable_properties的值

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。

你能试试这个吗？

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