推荐答案

您的

 name = business

尝试从表 sqlite_sequence 中删除，其中 name 列等于假设的 business 列.如果您试图从名称列包含 value "business"的 sqlite_sequence 中删除，请尝试

tries to delete from the table sqlite_sequence where the name column equals a hypotheticalbusiness column. If you are trying to delete from sqlite_sequence where the name column contains the value "business", try

String query = "DELETE FROM sqlite_sequence WHERE name = 'business'";
